The 1974 or 1977 chevy service manual actually has pictures of all the factory adapter plates and which transmissions and transfer cases that they fit. Obviously these are pre round pattern, 5spd, or alum transfer cases.
For fun I have run (still own it sitting in the barn) a 465 to NP203 factory adapter. that was a real nice setup if you lived in an area that had alot of black ice during the winter.

I have been trying to figure this out as well. I picked up a 70 SB 4x4 but it has the M330 in it, with the 205, since it has the factory (dated 12/30/1969) NP205 it must be the 10 spline input shaft. But can't figure out if that is the case.
