So i swaped my np 207 that didnt work cuz of the chain.... i swaped it for the 242 and everything went pretty good other than it was a pain in the *** i figured out a way to hook back up my speedometer and got a drive line hooked up and all that good stuff.... but when it is in 4 wheel drive you can see that the front drive line is being torqued on but no power to the tires is this due to the locker thing on the 1986 command trac? if so how to i fix this or rig it to make my 4x4 work??????

 

Did you ever figure this out? Do you have a write up on how you made the 242 fit I have an 86 with the 207 and want to make the swap. I have the vacuum disconnect week so I just fabbed a quick disconnect cable to fix it for mine.
