Hard to tell from the pic. The one on the far left looks like it might be the same as the BBC bracket I have here for a 72. That said I dunno if the 69 / 70 are the same as a 72. 3rd from left is a questionable call that might be SBC but the 72 BBC uses a similar bracket for the rear of the compressor. Same as before not sure about the 69 / 70 being the same as a 72. Those other two brackets...BEATS ME!!!!!

 

I can tell you for a fact those are not only incorrect for 69-70. They also don't fit 71-72 big block either. I have a 71 big block with a/c and none of those brackets match.

These are correct for Late 70 to 73

 

From what Ive seen on ebay, the left one & both center ones are SBC, the right one Ive never seen before.

These are what Ive been told are exactly NOS correct for 69-70 chevelle big block only;

Any other opinions? I want the correct ones since my car is going to be restored to factory - or as close as I can get.

 

Yes those are correct. I may have a set for sale in about a month or so.

 

Dibs on them! How much?

They look like these right?

 

As I said the picture quality isnt that good. If the pics of the sandblasted / cleaned pieces are pictures of the same type of pieces in the first post here then I agree none are BBC parts.

 

Dave,you have email with info that will ans your questions.

Also,they are repoping the ac brakets & they can also be found farily often on ebay too,sometimes cheap sometimes not depending on who's bidding a the time.

Chk your email & let me know if it arrived ok.

Those brackets go for about $300 a set or more. They are not easy to find.

Do they look like these? Are these the ones your referring to, or some different ones?

 

Scott Wheaton sent me pix of his numbers matching 70 SS he restored & the brackets on it look just like the ones in the pictures. He says those are correct for the 70 & they look just like his, so if they are not, does anyone have pictures of the correct ones?

Which one is different? How is it different?

 

I don't recall which one it is, but one of them is listed as camaro only in the chevy parts catalog I have that is dated october of 1970.

 

After all this talk, I feel it is a good idea for someone to list pictures of all the correct brackets along with part numbers. Since most of us buy stuff like this off the internet, if we had that info we could ask the seller to provide part numbers along with pictures so we can verify that the parts we are buying are correct :yes:.

Anyone willing to provide that info?

 

If you still want the later style big block a/c brackets then i have a set with the correct fasteners. PM if your interested.

 

Not all of them have the part number on them.

 

Ok so post pix of them & part #s on the ones that do.

 

This is the picture of the brackets i have offered.

Assembly manual pics

Here are the brackets on my 71 chevelle 402

If that isn't enough proof here's a pic of my friend Johns' unmolested, and documented 71 chevelle survivor.
Other than bolting them up to the your engine for you, i don't see what else i can do for you.

 

69 and 70 are different from the ones you are showing. I don't have pics of them to post, and the sets of brackets that I have are packed away nicley in storage.

Yes that is true. But he asked about the later design which i have posted earlier today. Also the later design was used on 1970s just don't know what month.

 

Actually, I AM interested in the earlier brackets because I have been told that they fit 69 & 70 only. From what I am reading here, the "later" brackets WERE used on the 70 models, but later in the build, correct? does anyone know what month the later brackets started being used?

I still would like pictures of the 69-70 brackets & part #s too if possible.

lrdvdr41 would you be willing to pull out your brackets & provide that info? Also, do you have a set of brackets to sell?:yes:

Bubba, thanks for all the info & pix. I bought a set of late model ones off ebay last night for $85 shipped, but I may need the early brackets depending on what month they switched over.:thumbsup:

 

My Gm of Canada Parts book lists 70-74 chevelle brackets as all the same!

#3969917 Front support compressor bracket

#329227 Rear support compressor bracket

#336054 Front compressor bracket

#3999280 Rear Compressor bracket

#3969910 Compressor brace

PLEASE NOTE! I am looking for a #3969910 compressor brace-any condition!Thanks

Keep on cruising! Dave.

 

The late model brackets were never installed on a 70 on the assembly line. Look in the assembly manual.

Sorry, I am just not able to access the brackets at this time. The part numbers listed above are not correct. I bought a 70 caprice in 1990 for 1700 just to get the brackets I have, and I'm not selling them.

 

If you take what you see in the assembly manual as gospel then you are in for LOTS of surprises. The assembly manual you have in your hand is a portion of what they used. I was talking to friend whos' boss was an engineer for gm in 1970 and he stated that the REAL assembly manuals were 6 foot long mounted in a binder on the wall. Each model had its own binder. Alot of the things GM did as far as mid year changes you don't have documentation of.

 

I think they are correct-why else would they be in a GM Parts book that the dealer used!Keep on cruising!Dave-p.s some part # were different between Canada and the U.S.!

 

Wow sounds like a big mess to me, but interesting info. I guess most of us will have to go with the later brackets since we dont know what the earlier ones look like, & probably cant afford them. I guess it is up for discussion as to whether a car is correct or not. If they did use the brackets toward the end of the 70 model year, then I think I will be ok because my car was built in late May (4th week) & there was only a couple months before the transition would begin to take place into the next model tear. I have worked for Ford before & they shut down thier plants in the first 2 weeks of July to change over the next model year equipment & get it up & running. Then the last 2 weeks was a slow ramp up in production to reach full potential by the new release in August. If that held true for GM in 70, or close to it, then I feel I am fine using those brackets. Plus there are numerous documented 70 SS numbers matching Chevelles that have these brackets on them, & some were built before mine.

 

Later parts books show parts that FIT other applications, noot what was INSTALLED at the time. The parts book I have is 70 model year specific and was revised in Jun 1970. Rumoras get started that stuff was used by people trying to sell stuff and come up with a line of BS to try and pass something off as correct that isn't. I'd like to have one of the 70 experts such as Dotterer, Nelson, or Peters chime in about the correctness of these later brackets being installed on a 70 from the factory, as I do not beleive it to be true.

Exactly whom are you referring to, me? As far asking Nelson that will be the next thing i do. It will be easy as he's the one buying them from me. I didn't come up with the idea that the brackets were used on later 70 chevelles. I have a 71 and in the beginning of 71 they used a water valve for a/c cars in the middle of the year they changed to a check valve and discontinued the water valve. This was a mid model change this was done all the time. At what time in the calender year do you think cars are changed. New model years come out around september of the previous year. To think that they didn't use parts prematurely. Who's to say they didn't change the design in 1970 but coudn't implement it until late 70 so they could use the existing brackets and claim a loss. Have you seen the difference between the two. The 69 to 70 brackets are weaker design from a structual standpoint. If it is indeed a FACT then i will be the first to admit i was wrong. However i need undeniable proof not opinion which is all you have offered at this point. :yes: If its 71 or 70 i really couldn't care. Not trying to rip anyone off and i was the first congratulate him when he bought brackets from someone else.

 

Slow your roll. I know what the parts catalogs show that are from the times these cars were new. I know what I've seen on ORIGINAL UNRESTORED UNMODIFIED cars, and every one I've seen has the 69-70 style brackets on them. I don't care what people have on restored cars. If you read what the man is asking for, he is trying to get the COPRRECT brackets for his 70 SS396. Late model truck brackets will work, but that is not what he is looking for. The correct style is the 69-70 style that has the large bracket that loops over the valve cover with a hole for the PCV valve. I'm just trying to provide the information that I know to be correct in my 25 years of learning about these cars.

 

Slow your roll.

Never heard that one before. lJust the same I get where you are coming from.:beers: I realize what he was talking about and until i saw his car and how original it appeared which was after i posted my little diatribe i now insist on finding the right brackets for it. I understand the need for correct parts. Hell i bought an a/c setup just for the 772 fan. When i told people i was recovering my seats in vinyl i was asked why not leather. Because that's not what they used back then. The same thing when i put in original power windows and locks also the air cleaner and painted valve covers.

These are the correct style brackets. Ask him for the part numbers on the brackets and I'll tell you if they are camaro or Chevelle.

HOLD ON NOW! I included this picture along with one of my very first posts, & was told these were a mixture of brackets, some small block, & some big block! Now they are correct? I am really confused!

And to make matters worse, I just emailed the seller of those brackets & informed him that they are wrong & referred him to this post! Now Im going to have to email him back & apologize.

Can we PLEASE get an expert on this thread to confirm what the CORRECT 1970 SS 396 brackets are!

GREAT info & feedback though! It sounds like this is a thread that will be referred to alot in the future, once we get clarification for the gurus!
