Is it a 3-speed (shifter on column) or a 4-on-the floor? If it's a 4-on-the-floor, is Reverse to left [toward you] or right [away from you]? If to the left it's a 420, if to the right it's a 465.
The bell housing is the heavy cast iron part on top. The flywheel cover is the sheetmetal guard on the bottom. Don't lose it, they're hard to get now. Did both break?

The early truck & car bell are 4.684 dia hole(4 11/16). Try Jegs, & look up Lakewood bells, it gives dimentions). The 68 up truck has a 5.126 hole, so just a thought......if you are running a Saginaw 3 spd(7 bolt sidecover), you can swap the front bearing retainer tween the car or truck 3 spd trans(saginaw), & use either bell.......crazyL
