How many of you guys have ever heard of a ratio like this in an f body? Thats apparently what my mechanic is installing in place of my worn 2.77's. Oh well. Hope it turns out ok.

They made 10 bolts in 3.08 and 3.23. I don't know what ratios came in the 9 bolt. You should get him a calculator for Christmas.
