You can get it shortened probably.

I had a beefier carrier bearing assembly than the stock 1/2 ton put on my C10. A 3/4 ton mount and newer/bigger style carrier bearing than stock.
Original carries are flimsy to say the least on the 1/2 tons with some extra HP they will twist and make Allot of noise when they do.

I'll post some pics....

SWB's have a 1piece driveline.

most SWB had a 2 piece shaft.
Assuming the engine and tranny are the same between the two trucks, the driveshaft will be 12 inches too long

They have both depends if the truck has a manual or auto trans.
My 68 SWB has a 2 pc with the 350 auto, picture shown the bigger 3/4 ton carrier assembly
The 71 SWB has a 1 pc with the manual trans.
