Changing to 3/4 rear?

[s10 racer]

I bought a complete 3/4 rear-dana . came out of I think 96 chevy truck. It is complete drum to drum-leaf springs and all. My question is will it fit directly into my 89 chevy 1/2 ton 4X4?I think it has 3.73. I know I gotta buy 8 lug rims. What about the u joint-yolk etc? Thanks in advance
