My friend has a 79 chevy with a th400 trans with a 203 case. I found him a tranny out of a diesel but it has a np208 on it. Are the tailshafts the same for these? Corse spline? length?? I just want to make sure they will interchange.

All will be 32 spline but I believe the lengths are different. I'm not sure about the 208 but the 203 application should only stick out about 1.5" from the trans case.
