Okay thank you so much for the reply , it confused me pretty bad when I ordered a-body lower and upper ball joints and they were both way to small lol , thanks for the help guys and is there anyway to tell the difference between 72-73 bushings
Yes. In '73 Mopar started using a lot of the same parts across all the different platforms (well, except C-bodies and trucks). The ball joints, wheel bearings, rotors, caliper mounts etc were the same for A/B/E bodies and a lot of that stuff will interchange for the earlier cars.
Honestly, you already have the large bolt pattern wheels and the right ball joints, I would just get a set of disk spindles and go with the 73+ disk brakes rather than buying all the stuff to refurbish the B body drums. That's just me though. Obviously the cost will still be higher to go to disks, but if you have to completely refurbish the drums you're probably gonna spend close to half the cost of the disk upgrade, and still have B-body drums.
