I'm swapping a TII suspension into my 86 NA because a) i have the entire TII rolling chassis, b) it seems easier to swap the entire suspension components to get the 5 lug/ 4 piston brakes than tearing it down to smaller component pieces, and c) i want the LSD for later plans. I have spent the last 90 minutes on search and have learned all kinds of interesting facts about TII engine/trans swaps, and every other kind of swap that there is but i cant find a definitive answer about drivelines.

Will i be able to use my NA driveline to the TII rear end by drilling new holes in the flange?

 

either swap everything onto the tii, or vica versa, TII and GXL had the best suspension, brakes etc. Use all the you can off the TII

 

A custom driveshaft will be needed.


All in all the TII driveline is far superior. I suggest swapping it up to your NA engine.
