SWB 4WD 1994 B4000 rear one-piece drive line lengths

[badmts]

Well the front SPARTAN locker went in without a hitch ,the front drive-axle U-joints you guys recommend (760x) look awesome and work great but in doing these upgrades we discovered rear driveshaft issues-It is wallered out and ready to EXIT STAGE LEFT! So I need a replacement,the consensus at the shop is get a used one piece like I have and have Drivelines NW lengthen it to match the 6in lift. Does this seem like a good plan? And which donor year,bed length or 4x4 or 4x2 will work. I am seeing lots of SWB 4x2 on CL but thinking they won't work THANKS

What is the wheel base of your truck now?

You will need a shaft from the same wheel base 4x4 truck.

2wd will not work.
