it depends on the engine and trans the car came with and if it had an optional ratio, but the most likely is a 2.41. It could also be a 2.56, 2.29 or the sexy 3.23.If it was a 442, it would be the stronger 8.5 rear with a 3.73.
I would suspect you had the cover off the change the diff oil and you could have checked the numbers of teeth stamped on the gears to calculate the gear ratio....

Check out my 3.42 7.5" ring and pinion in the auction link page. Asking $35 and it ships cheap.

I think the 2.29 was, not the 2.14. I dunno what GM was thinking with that gearing....maybe they thought people were buying them to go land speed racing? :lol:
