Ok, pretend I know nothing. Your saying I can change the front bearing retainer from 5.125 to something smaller? this is easy? Once done i can use a more common bellhousing?
Yes, you can switch the input bearing retainer from one that’s 5.125” to one that’s 4.8”. But you have to remember that there are two different 4.8” diameter input bearing retainers, one has a smaller bolt pattern (307 bearing). The one you need is the 4.8” diameter retainer that came with the 308 input bearing and has the larger bolt pattern.
