I need to know what length output shafts came with what transfer cases and adapters for TH400s. Off the top of my head, I know GM used the following combos Th400/ figure 8 adapter/ short 32 spline input 205 Th400/ 6 bolt round adapter/ long 32 spline input 205 TH400/ ? adapter/ 32 spline NP208 TH400/ ? adapter/ 32 spline NP241 TH400/ expensive adapter/ 32 spline NP203 What I dont know is the output shaft length of the trannies. Which of these will interchange? I believe NP208s and 241s use the same adapter and tranny output length but I'm not positive. What about other case and adapter interchangeability? Specifically, I want to know if a 241 will bolt to a 6 bolt adapter/ long 32 spline input NP205 version TH400, maybe even with the same adapter?
