I have the 12" B body spindles but now I need to put on the matching Master Cylinder from the B body. The new MC is the full size type and looks like it would hit the hood. Any body done this before? Thanks for any help.

I would just run the original disc master cyl for that particular car. Is this for the '78 camino?

Be careful with the B body spindle conversion. It has LOTS of bump steer!

I'm doing it this winter, and from what I've understand, the bump-steer is really only a factor when you hit BIG bumps while driving aggressively. Under mildly agressive street-use, it's a great upgrade...

Correct me if I'm wrong :confused:

Check out my web site for the 12" install. I have very little bump steer unless driving through a pothole I shouldn't be in!

I love this swap!

Yes, it is for the 78 EC. I believe the B body MC has a bigger bore not sure by how much. The right front seams to grab first and I have change all other components I wanted to see if the B body MC made any difference.I did the conversion about 2 years ago, I used the stock HD springs (450 lbs) but would like to drop the front a few inches but I can't until I find a pair of the Regal T type aluminum wheels. Now there are a pair of the same style up front but they are 8 1/2 wide with a 3.75 back space which means they stick out past the fender.

The whole bump steer thing is hype. I have F body spindles and with some very simple and inexpensive mods bump steer is not an issue, and we have some of the worst roads in the country.

Well, unless they haven't invented asphalt where you live, I'd say the Rhode Island has you beat. ;) :D But, I have Buick station wagon spindles on my '71 and have not noticed any bump steer issues either.
I'm sure there are bump steer problems but not enough for me to notice.

No we have asphault.....except for all the big chunks of it missing along the highway. I can't drive certain stretches at all anymore, bottoming out on the croosmember and frame rails at 65MPH+ sucks!

Thanks for the tip on the rims.

78ss: i am trying to put discs on my 66 chevelle. i have a 79 elcamino in my yard. i took the spindles off the elky and they look similar to my 66 drum spindles. i was wondering if u knew if i could put 79 spindles on a 66 ???

I use to have a 70 Chevelle with disc that I changed to the 70-81 F body spindles. I am not sure if your swap would work, I would contact Hotchkis or Global or even do a search here and see if anything turns up. The only problem I really had was that I used the factory upper control arms and the shims were maxed out to keep it aligned because the new spindles were taller.
On the 78 I am using the Poleposition adjustable upper control arms, half the cost of the other guys uppers and no shims to mess with.
The A/G use a 10" disc, the F bodies use a 11", the later B has 12" which is what I have. If you are going to go through the mess of the change over I would definitely consider doing the 12", it is well worth it. It cost about $1000 including the new uppers and rebuilding the front end. You would have to add a combination valve of some sort to your system.

Can I get a link to these Pole position upper arms? Do they come w/ poly bushings?

Assuming the aftermarket arms require B-Body or F-Body spindles, do you buy ball joints for the corresponding spindle or do you buy them for the A-body? Thanks

TTT!!

I believe the site is Poleposition.com, this is the #303-286-8555. Mine didn't come with bushings, but some of them do. Looking through my receipts it does not say which ball joints are used just part numbers. I did the change over the way Hotchkis outlines it, check their web site. I want to say the ball joints are the same but the tie rods ends have a different thread. All this was 2 years ago and I can barely remember last week.

Thanks for your help, 78. I searched around on google and found those units; the correct website is actually www.polepositionrp.com (http://www.polepositionrp.com) in case anyone else needs it.

Ok, just a silly question here, but doesn't the 78 year already have the taller spindles, so there wouldn't be any changes? Is there a difference in the A-body Versus B-body spindles of that year?

I ask because some time in the future I'm going to build a 3rd gen Malibu and thought they had the tall spindles already. I was planning to swap in the B-body spindles for the larger 12" brakes tho...

Thanks,
Bill C.

No, the G bodies do not have the tall spindles.

There is no A body the same year as a B body.

You are planning a 5th gen Malibu I gather, a 3rd gen would be 68-72. No you cannot simply swap the B 12" spindles to a g chassis, it is just as invloved as the older model swaps.

The B spindles are 1" taller than A. When I first did the swap I tried to keep the A upper control arms but it could not be aligned. I have a set of GN wheels on the way for the front so now I can lower the car, probably use the Hotchkis springs.
