swapping a 73-87 rear end into a '67...who's done it? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I searched through a number of posts, but couldn't find the info I was looking for. I have a '67 C20 with coil spring rear. I bought an '81 C30 dually. I'm going to swap the front crossmember over, and going to swap rear ends too. Any tips for the front crossmember or rear end swap? Thanks

I put a 70's gym corporate 14- bolt
full floater in my 71 k20 .

I moved the passenger side
shock mount and used the brake lines and wheel
Cylinders off of the original eaton hO 52 .

The leaf spring mounts were the same spacing. I used new u-bolts .

The emergency brake line was the pain.

I bought a new universal for the 14 bolt.
