need help with rear setup

[erikh09]

I was looking for some guidance regarding the rear setup I am looking to go with in my truck. I have never been letdown yet on this site so this is the only place I turn to. I am building a 67 GMC 3/4 that I am converting to 1/2 ton. Long story short I am picking up an 83 or 84 chevy truck that was going to be scrapped and would like to use the rear out of it. It is a 5 lug 10 bolt with 4 leaf springs compared to my 8 lug 10 bolt with 9 leafs. Main question is will it fit with little modification? I know anything can be "made to fit" with a hammer, torch and a little aggression..
Any help would be greatly appreciated!
