From what I read about this 697 bell housing there are two types and it depends were the clutch fork pivot ball is located. If it's mounted in the top position of the mounting boss your good to go and if mounted in the lower position in the boss it puts the clutch fork in the wrong position . This according to the four speed convention site.
Also from 4 speed conversion site......(look up bell housing 464697)
If 621 is cast on the clutch fork stud boss, It's the same as 3899621.
If 697 is cast in the clutch fork boss this bell housing is specific to
1978-87 A and G body.

Excellent point, and that appears to be the difference between the 3899621 and the 464697 castings. By just a quick look on ebay, all the 697 bell housings all had the ball in the top position.
