The easy button for your truck is the 1ton SRW corp14. I will bolt right into your 3/4 ton, you only need to change the shock mount tabs. Basically no fab, you could drive to welder with no shocks and have tabs welded in if you don't weld. And have some zero rate leaf blocks on hand. I forget exactly but I think I ended up 1/2" one way or the other with the drive shaft length. Very close, near non issue. Read the link that Mongo posted from pirate, it is an excellent read. You will then know which year you want, base on neck down, brake drums with no axle pull and that sort of thing. Good luck with the DRW!
