Yep, the output shaft on the 700r4 4x4 trans is different than a 2wd version. You CAN change the output shaft but that requires trans disassembly. Swapping in a 2wd 700r4 is a fairly simple swap, probably a trans x-member move (the mount is a couple inches difference), if you currently have a 9" tailshaft on the th350 the driveshaft length remains the same, and a little wiring to control the lockup.
