My first post, but I'm sure not my last. My son and I are starting our first rebuild together - a 65 stepside. He is 14 so we have a couple of years to get it done before he starts driving. I came across a 1984 1/2 ton chevy - transmission's shot and the body is really rough, but it was free. I've learned through these forums I can do some upgrades to the 65 from the 84 - crossmemebr swap, power brakes and steering, etc. Swaping out the front gives 5 lug up front, but 6 in the rear. Can I just swap the rear end out of the 84 into the 65 to give the rear 5 lug?
