The only 10" drums with the 4 1/2" bolt pattern used on A body cars were the rear drums. All 4 1/2 bolt pattern front brakes were disc brakes.

The 9" 4 wheel drum brakes used on A body cars are all 4" bolt pattern. These 4" bolt pattern 9" 4 wheel drums were available up to the end of the A body production in 1976. The upper ball joints have different size studs between the disc brake A body cars and all the front drum A body cars. Gene

Obviously I'd need calipers etc. What do I need to scavenge for my 73 drum car? Thanks guys. I appreciate it.


I always point folks to this article.

You'll need disk brake spindles and believe it or not, E body spindles will work! If you don't mind 15" wheels, the 1976 up 11.75" unicast cop disk brakes are the bomb to do on the cheap, provided you can source the calipers and disks still. If not, there's info on stock A body disks in that article too. I did this swap on the Bee. Easy Peezy.


I’m listening.
