Steve,I would suggest that the bell housing for compact Fairlane etc with 3 speed manual from 62 thru 64 that uses the inner bolt pattern that all later top loaders etc have but don't normally use would have the diameter on that front bearing retainer/clutch release sleeve that you require the dimension from, soo if you can find a 3 speed trans from one of those to measure it might help...check it against your bell housing dia to be sure...why can you not simply measure your bell housing and work off that?
