Auto and 4speed crank

I have 2 engines in the garage one auto one 4-spd I just measured depth. Both are about 2 inches from bottom to end of pilot register. One is finished for pilot bushing the other is not. (Hard to get precise, they are on stands)

You can get a bearing that fits in the converter register and is available at nearly any parts store it is a National FC-69907 and that number can be converted to Timken etc.
