Slant to V8 transmission adapter

If it is indeed intended for a 727, a 904 won't fit. The bellhousing bolt pattern is the same, but the starter location is slightly different.

I know this because the adaptors that mate the early hemi's (think 1950's) to later transmissions are for 727's, and its because the starter interferes with the engine with a 904. Much to my chagrin, because I have a couple 904's that will soon be extra and a few early hemi's which can't be made to play together.
