Default Disc Brake Conversion Kits and Rally II Wheels

After owning my 69 for over 32 years I am ready to convert to disc brakes. Researched the forum and did not find good answers about which kits work with 14 x 7 rally II wheels. I want the install to go smooth with no mods and I am not wanting to hunt for different wheels. Anyone have good luck with there project?

I have 70 GTO spindles and calipers on mine and have no problems running a 14x7 Rally II with a 235-60-14 on the front. The spindles and calipers are the same for a 69 F-body and 69-72 A-body.
Good luck

Todd, it's all about the caliper bracket. If you use a GM caliper bracket, you'll be able to run 14" wheels. If you go aftermarket, that bracket will rub inside the wheel. I've done it on a 68 Camaro. That is I machined the spindle's top bolt boss .615" for it to become a disc brake spindle, installed GM back plates (you can buy repro, they cost next to nothing but are kind of thin), installed used GM caliper brackets, bought calipers and rotors and 72 Monte Carlo brake hoses (Yes, 72 Monte Carlo)at the local auto parts store. I bought a booster/MC/proportionning valve from inlinetube.com.

Thanks for the info. Looks like I need to start hunting for GM brake parts.

I also want to switch to disc. Would front rotors and calipers work off a 73 El camino?

look at a company called the right stuff. i have right stuff kits on my 68 and 69 firebirds. both cars stop great and everything is brand new and looks correct.booster,master,rotors,calipers,stainless lines,spindles everything needed. all brand new. running 14 7 rallys on both cars. the caliper brackets where the only problem as stated. the 69 i used a gm set of brackets because the ones from the company where hitting. the 68 i used the companys brackets. i grinded the heck out of them to get them to clear and still no good.tried several differant 14 7 wheels all fit the same. took the brackets with me to the next swap meet the right stuff was at and the owner gave me another set .this set fit ok on the one side but still had to grind the top of the other. seems to be a little variation in the shape and bends of the brackets between venders.worst case you might have to look for factory brackets if you cant get theirs to work. if you are doing a points car or high dollar restoration guess it would be worth buying a used set and having everything replated and rebuilt but for the average restoration i am sold on the new repro stuff available. just my opinion because iam happy with the looks and how the cars stop now but to each his own.

No, it will work all the way to 72. 73 and up is a different animal.
