7 1/4 Posi??????

I know I can probably look up the part numbers, but off hand do you know if the earlier 8.25’s are the same/different?

My ‘71 Satellite Sebring Plus has an 8.25 in it, that would be a nice option for an upgrade without swapping the whole rear end.

I know there are apparently some case differences, like the later 8.25 case was ribbed heavier than the early, but other than that I don’t know.
Sorry.
