c10 to c20 rear end swap

Im getting ready to do this swap. And looking for any advice before I start.
I have a 68 c10 parts truck, leaf spring. The c20 is coil with what I just determined to be 5.14 gears, woohoo... not. So since the parts are not readily available for the gear swap, my best option is to swap out the c20 rear with the c10. The c10 has disk on the front which I will steal later anyhow.
I know I will need new perches and the u joint and length of drive shaft are probably not even close, but figured I cant be the first one to do this in 45 years.
Thanks
oh tranny is a muncie 4 spd. The 5.14 make it a great granny low 1st gear. lol
c20 rear end is the ho52 i believe.

Im doing the same swap. I bought a 70 c-20 and swaping in a 70 c-10 rear end and a 72 disc set up in front. I am also adding power steering and power brakes.

My c20 has the power steering, but i too will be adding the power brakes. Im lowering and basically taking the 3/4 ton right out of it, but its what I want..
I might have the power steering setup for your truck, I think my c10 is setup for power steering. Let me know if you need the column.

Wow. 5.14s with the 7:1 first in the Muncie. You could probably walk faster than that at idle..
