Hey guys Ive been asking around trying to change up my front end to get those front duals and grill. Ive got most of it worked out. The 70' grill extensions will fit fine on a 71' right?

I am pretty sure that you need a 70 Radiator Core support panel to do the switch right. There may be some other things also. It is a lot more work than you may think. I am thinking about doing this now that I need a new Core support, but I am thinking of just running one light on each side and use the other socket for kind of a ram air effect straight in to the turbos (when I put them on)

That was going to be my next question, I was just flipping through the OPG catelog and came across the radiator support panels and cringed! More parts! Which is always good, but $$$$. Do you know if the 71' can be modified, it seems like it would make it alright. So far what I know I DEFINATELY need, or whats needed to do this is:

Fender Extensions
Headlamp Bezel/ chrome housing & gaskets
New wiring harness (modify whats there)?
New front grill (coming anyways)

I think thats my parts list, I hope I wouldnt need much more than that. I really want to do this conversion, My 71' is far from a stocker I love the rear end on a 71' but the 71' front end is bad bad bad! graemlins/beers.gif I'd like to get the most of both worlds here. I guess the good thing is here I can sell my 71' peieces when they come down so if anyone needs them let me know.

You may be able to modify the 71 core support panel, but I'm not sure, maybe someone else with some experience in this might know? I suppose if you REALLY wanted to you MIGHT (I'm gonna get hell for this...) weld the 70 fender extensions to the fenders from the inside. It might be hard because the extensions are pot metal (right?), but I have seen it done. graemlins/clonk.gif It's not the most effiecient way to do it, but it can get the job done. If I was going to do it I would do it right and get the Core Support for a 70.

the fenders are different on the extension mounting areas, you can drill out the panels and weld them in your own fenders if you find a donor set of 70 fenders.

This conversion is a lot more work than it first appears. We did one to a guys 72 back in high school, but we started with a complete 70 front clip. Basically the only metal that will interchance is the hood. The fenders are different dud to the fact that the 70's had the marker light in the lower front part of the fender. The extensions are of course different, the radiator support is different and would be a pain to modify. The grille, bumper, inner fenders, wiring harness are also all different. So the best way to do this conversion is to purchase a complete 70 front clip inclusing the wiring harnesses. Good Luck

70 fenders,
70 core support,
70 fender extensions,
70 side marker lights,
70 headlights, buckets, rings...
70 valence panel,
70 grill,
70 bumper and brackets,
70 corw support center brace, and end brackets,
70 light harness.
all these parts are unique to 70 only.

Are the 70/71/72 fenders the same on where they bolt to the car and the core support?

Sounds like your trying to scare me away from doing it smile.gif I was bidding on Ebay for Fender extensions and it turns out he lives about 20 minutes from me I went down to Rocklin (near sacramento) and picked them up turns out he had the radiator support and the bezels, and I was replacing my grill anyways. These were the things I thought Id have most trouble finding on a budget but now that Ive come this far im almost ready to do it! As for the fenders themselves the only difference I can think of is the turn signal markers are on a different section lower down on the 70' than the 71's? Either way I dont plan on running turn signals I dont think I'd get much hell from anyone around here. I got an awesome deal on my parts by the way. New Chevy hook ups are always good.

70s had their front turn signals in the bumper. You may be ok for a while, but eventually you will get a pr*ck cop that will pull you over for no signals in front. You also won't have running lights in the front without the 70 bumper. I was thinking about the conversion, but I came across a great deal (so far) on a 71 radiator core support, so I guess I'll be sticking with the single lights.

Yeah it is alot of stuff to go through and buy. Especially when pricing it all at Ground up or NPD, etc. It added up and was very intimidating. Then I found this guy that had a garage full of stuff he didnt need in great condition so I am very excited to start this project. If I see a cop from the front and im planning on turning I will just have to go straight ;) The only thing I will have to figure out is the wiring harness, or just pop a new one in. Or run single lights until I get around to hooking up all 4 of them and the highs. Im sure I'll come across alot of little things.

If you see a cop you could always use hand signals. Personally I hate it when oncomming people don't use turn signals, especially when I'm at a stop sign.

Yeah I just cut those little panels out. The ones on the tips of the fenders. They were spot welded in, I have no idea what these little panels were called and I didnt see them in any books. Anyways heres an update!

I got in my radiator support and put back my radiator mounting and the radiator and connected it to the inner fenders and all that. It looks like a front end again. I think the toughest part is out of the way. The one I bought is clean but a little crooked I will have to give it some heavy slams and kicks to bend the bottom have in a good 2 inches. Not a biggy smile.gif

I am at the point of wiring in my headlights, I just bought the set of 4, good thing about the regular lights they run on the same 3 prong wire harness. The high beams on the other hand will need some re-wiring which i have no idea what way to do it yet. I know I should get a new wire harness which I might end up doing unless I can rewire these H-BEAMS. :eek:

For the headlight mounting. How do they stay in? I think I have everything but the bezels. The lights go between the bezel and the fender extension and then I guess it just all mounts to the fender itself and the radiator support? :rolleyes:

It sounds like it is already too late... a 70 front end with 71 rear. I think it will look strange but thats just me. Thats true, everyone has 70 Chevelles. That's the reason I don't like them. But to each his own, right?

Hey pnut... here is some 70 headlight bezels on ebay for $1.00 http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&item=2453076675&category=33654 I don't think you have them yet?

The link was for Fender Extensions not the bezels smile.gif The only thing I need I THINK is the bezels and im going back to the same guy to pick those bad boys up. Everyone does have a 70' I can see how some would think it looking strange. I didnt think Id actually go through with this either. And it ISNT red smile.gif Its dark blue, nothing fancy... it's gearing up for a new paint job when it stops being 30-40 degrees. And I need to decide on paint. :D

Don't know what I was thinking saying bezels... I think it's because I saw a set for auction before I found those... Here are the bezels... http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&item=2452320827&category=34204. They arent a dollar though.

The headlights are held in by a retainer ring (metal band) that is in turn attached to the radiator support by 4? screws, This is also where your beam direction adjustment is made. The bezel is then attached over this to the headlight frame. Is that what you were asking about ?? graemlins/waving.gif

As far as mounting the headlights, I had trouble finding the correct plastic nuts to attach the headlight adjusting screws to the core support. You need 2 plastic nuts, 2screws and 1 spring for each headlight.
Good luck.

Ron You can get any fastener you will need from OPG including those square plastic nuts that Ron mentioned graemlins/waving.gif

Ahh, so ther is another mounting ring between the bezel and fender extensions? I’ll flip through my catelogs, what are they called exactly or a part number/ link? I got my bezels tonight smile.gif not bad 4 for $60 good as new.

headlamp mounting rings. Looks like everyones got em' for $20 ea. Thats a quick $80 plus S&H/ tax smile.gif Then again I did find NPD was the cheapest place, I think they have them for 13.00 and 13.10/ outers ea. "headlamp mounting ring" Wonder why such a difference. If im looking at the right part. There are also Headlamp capsules/ sealed beams

through NPD. There called Headlamp retaining ring part# c-2731-202 and they are 11.50 ea. I think these are what I need. There is also a "Headlamp mounting ring" which looks similar, and a headlamp capsule. 2002 edition catelog page 75-76 is anyone has it or online.

I went and checked out a local wrecking yard that said they had a 71 malibu, so I went and checked it out and it was a 71 but the front end had been converted to a 70. EVERYTHING was changed in the front. The radiator core support all the way to the hood latch assy was differnt. Fenders were different too. Not a bad car though missing interior but car was solid and has a 12 bolt. only 800 for the whole car.
