Np203? ? ?
« on: June 17, 2016, 08:49:10 am »
Recently purchased a new tranny married to a t-case. I believe the t case is a 203 and not sure if it work for my setup. If anyone out there is using a np203 in a mid 80's half ton and did you have to modify anything to bolt up the front drive shaft???

in 77 ish they changed how the driveshaft bolts to the transfer case (yoke vs flange). being you would probably have to reuse the 203 driveshaft it shouldnt matter (due to length difference in the transmission and transfer case) hopefully you got the driveshafts

No drive shafts just the tranny and tcase, but it does have the flange just like my old old
