Default 8.2 or 8.5 rear ??

I would like to change the pinion bearings in my 71 GTO and would like to get all the parts ahead of time. Before I order the parts I need to figure out what it is... other than a 3.23, 10 bolt. Apparently it could be either an 8.2 or an 8.5 and have either a 25, 27 or 30 spline pinion. I looked at the original build sheet and my PHS documents but still can't figure out what I have. Is there an easy way to tell, without any diassembly or am I missing something in the documents I have? Also, are there any recommendations on where to get a rebuild kit/bearings?
Thanks in advance guys.

Glen.
