400/203 is one adaptor and output shaft.

400/205 early fig 8 bolt pattern to tcase is most comon and uses 1 output .

400/205 late is round tcase pattern and diffrent output yet.

th350/203 and 205 same out put shaft in tranny. but 2 diffrent tcase mounts.

sm465 early 85-90% of them out there are fig 8 style tcase pattern mounting and use 10 spline 4 speed only shaft.

you can swap inputs on tcase but 400/205 requires bigger bearing in case. 2 ways. bore out the tcase hole bigger. or search on here for the swap bearing part# that lets you do it with out borring the tcase hole out.
