Okay so here is what i have
1987 3/4 ton r-20
5.7L V8
350 motor
TH400 transmission
ALL HD ( According to the RPO)
Rear axle; has a 14 bolt with 4.10 gears
I also have a donor truck
1987 1/2 ton v-10 (according to RPO)
5.0L V8
700R4 transmission
Transfer case; Unknown to me ( I Do have pic)
Front axle i believe is a Dana 44 ( it has 10 bolts)
Front suspension is HD according to RPO
Rear Axle is a 10bolt with gear ratio is 3.73
Came with 35in BF good wrench tires
So my question is if i wanted to make my 3/4 ton a 4x4 could i swap parts from the 1/2 ton over all i really want is the 700R4 transmission with the transfer case and the front axial (with the "HD" springs) i do know i will have to change the front axles gears to 4.10 to match my rear but is it/ or should it be a bolt off and on job for the front axle or not? what other things should i take into account? Or is the donor truck just useless to me?
will upload some photos i thought might help
I do plan on using this to haul and some occasional Texas desert trails so some advice would help tons.
