I dont have a divorced case,nor do i want one, i am however using a 203 case and am going to convert it to part time 4WD. The hydroboost was off of a diesel but didnt they also use them on 1 ton duallys? I see classic industries selling hydrboost kits for street rodders.
Im just looking for cheap and easy answers to my 4x4 dilemas....i wonder if there are any?

I do have a running, driving 89 suburban w/ a tbi350, 700r4 trans and 10 bolt front and rear w/ 3.73 gears. Do they make stand alone computers for the tbi and trans? i could use lots of parts off of this truck and junk the rest. Havent had much luck selling it and i only paid $1200.00 for it last winter. Drove it all winter without so much as a hiccup, ran awesome.

What do you think guys, should i scavenge parts off of the sub and build my truck or go back to my origional plan and stick with the 350/350-203 case plan and sell the sub to finance the rebuild?
