For Those Doing Disk Brakes. 60-66

[1966gmc]

w00t,my buddy blew the engine in his 79 chevy and guess what,I'm buying it for a disc brake swap for 100 bones.Now my question is,the 79 has leaf springs in the rear like my 66 gmc does.I assume I could straight swap the entire axle assembly right?I sure as hell hope so lol

Yeah that would be the easiest way.

I've been following this thread from the beginning and just completed installing the complete frontend from a 78 GMC 1/2 ton to a 62 frame.
For me it was far less work to change everything over including the crossmember. I think I had to drill maybe 2 new holes in the 62 frame rails to get everything bolted in. I might mention, the frame rails on the 62 are shorter than the 78 so I had to fab a little to use the 78 motor mounts. I fabricated a mounting bracket to mount the powersteering gear from the 78 to the 62 frame. I installed a 4-link posi from a 70 Caprice on the same frame, which was a lot more work than the frontend. I'll attach pics in a few days. Great site, thanks for the tips.

I believe that the 79 rear end is wider then the 66. It will work as long as the spring perches on the axle housing are the same distance apart on both set ups.
