drum to disc brake conversion

[lolife99]

Without pics,... all this info could be wrong.
I remember trying to help a member through many pm’s back and forth for many days before he finally took some pics. In the end, his truck already had drop spindles, and it had been changes to 73-87 parts by the previous owner.

But I’ll be glad to help with any questions you have.
We just need to figure out what’s on your truck now.

I didn’t do proper research on this and bought CCP 2 ½” drop spindles from Summit for a 1967 C10 which is what the truck is. But the ball joints did not fit right on the spindles. I called Moog tech support (800-325-8886) to get dimensions on the upper ball joint shafts. The difference in the 67 and 71 is the small end of the taper on a 67 upper (#6024) is .588 and the 71 (#6124) is .551. The big ends are the same .702. So I had a choice to return the spindles to Summit for an exchange or get new ball joints. I decided to use 1967 ball joints since the 71 ones on the truck were bad anyway. I got new rotors and calipers for a 1972 C10 from O’Reilly’s.

I plan to use 73-87 front crossmember so I can use rubber bushings when I rebuild front suspension. Research all your options. This will change to rubber bushings (cheaper), front disc brakes, power steering, but will require 5 lug axles in rear.

I have a 1972 GMC C1500 cab and bed that sits on a 1969 Chevy C10 frame. I used ALL the 1972 disc brake stuff up front. It let me keep the 5 lug setup. Out back I used Moser 5 lug conversion axles. They are the correct length with the 1969 housing, but with the 5 lug pattern instead of 6 lug.
