[71blksuper4x4]

John, your demands sound pretty accurate for a reason to go 3/4 ton. If you are trying to find a front axle for it. I recommend a Dana 44 (D44), they were used up until late 70's, but don't turn away a 10 bolt out of an early 80's truck. There strength characteristics are not that far from each other and the d44 is just a little stronger. You can also convert a half ton d44 to 3/4 by using the parts from a 3/4, (hubs, rotors, etc.) should you find one out of a 67-72. I am not sure whether the 73-87 requires to move the spring perches. For rear end, you can't go wrong with a Corporate 14 bolt. Try finding a full floater if possible. These are cheap to find and for parts. These axles will easily hold any tire with a 4-6" lift. Now for transmission and transfer case. If you are going to be running a 402 BB and th400, you will either need to find a K model th400 (4x4 transmission) that accepts an $$$ adaptor to bolt inbetween the transfer case. The only way to use a 2wd th400 is by using a divorced transfer case. That is what we used on my 96 with the big lift kit on it. A divorced transfer case allows you to use a 2wd tranny with a very short driveshaft in between it and the transfer case. The only problem with one is you have to fab up your own shifter and linkage as sometimes these can sit far back on the frame. The best transfer case I personally like is a np205. They were stock in trucks after 70', but phased out in the 70's as a chain driven t.c. came out .(np203) I prefer the gear driven t.c. (np205) as it's a bulletproof transfer case, and less problematic then the 203. Trevor
