If you have the 4.80 register hole in your current bellhousing you can run the bearing retainer from a 70 or later heavy duty 4 speed with the 308 input shaft bearing. Same bearing the O/D trans uses. If you have the 4.30 register you may as well buy the O/D bell.
I don't have a bell housing yet, I am getting that I cant use an undersize bearing retainer, and that I can machine a smaller hole in a bell housing to the larger OD retainer size. but cost would be easier to just get a bell with the correct hole.

Look at post #7. There is absolutely zero need to machine anything. Mopar made SIX different bearing retainers. There's one that will bolt on and work for you.
