If you have the heavy duty Muncie SM465 they have the 5 1/4" front bearing retainer, all the rest are 4 1/8" so you will need a different bell housing.

Here's a link I got for transmissions they sell rebuild kits with complete instructions. I got a SM465 I'm going to rebuild befor I put it in my 68 C20.
