TH350 and 203 to 205 compatibility?

[the beast]

I've got to replace the transmission in the Beast. It currently has a th350 w/ a 205. I got a th350 out of my donor truck that was connected to a 203.

Will this be a direct bolt up, or will I need to change things on the 203 tranny?

203 and 205 same output shaft in tranny. go for it bolt it up.

All th350's were 27 spline,
SM465's were 10 spline, HOWEVER, 32 spline from 86ish and up
TH400's were 32 spline, can be either short or long output shaft

np205 had 2 front outputs, 10 spline and 30 spline..easiest way to tell..if thers a 1310 yoke, its a 10 spline.....if theres a flat flange, 30 spline...IIRC 77 ish and under was 10 spline, 77^ obviously 30 spline..

Thanks guys. My big concern was if the trannys were compatible.

I'll be running just the 205 for a while until I get the big axles in and the plate for a doubler.

This takes a major load off my mind. I need to get this truck back on the road.
