sm420 question

does anybody know what the bearing retainer size is? i'm doing a t5 swap and trying to determine what sizes i'll need to have my plate made or if i can buy a premade one from vintage metal works.

i know it's a pre 67 sm420 because it doesn't have a spot for a reverse light switch, but i'm concerned because it's in a 71 c10. As far as i know all 67 down bellhousing had the 4.686 bellhousing hole(or something like that) i'm THINKING the PO had changed it all out because the transmission doesn't wander in the bellhousing and it doesn't have an index ring. if i had it apart it wouldn't be a big deal but this is my DD so i can't just tear it apart to look. ANY info would be pure awesome i know you guys know the answer haha
