the information online isn't always right indeed. Pulling the cover will be my next step.
I will post again here after I've checked the ring gear bolts (CCW vs CW) and get the code / part number on the ring gear.
I'm trying to avoid buying parts I won't be able to use so that's why I want to be 100% sure of what I have prior to ordering parts.
Thank you all for your input. It is greatly appreciated.

From the research I've done, that's what my car has under it....Somewhere in the upper 2's as far as gearing. I've got a photo of it somewhere. 12 outer bolts but I understand that it's a technically 10 bolt 8.5" rear...Correct?
What did these come under?

Oldsmobile rear....
