2-series posi for 28 spline 7.5"?

Does anybody make such an animal? I can only find 3-series to fit that setup, and I need to keep the 2.73 ratio...

Auburn does. Pretty sure there's GM OEM l.s.d. in that spec too.

For sure they exist, I have a 7.5 posi with 2:71 gears in my Lemans. It`s not original to the car though, I picked it up about 15 yrs ago. I seem to remember it beign from a MC but I`m not sure

Thanks guys

I was looking at Summit, filtering by Chevy/GMC 28 spline all years & all axle models, and they didn't list the two Auburn units! Weird.

Sometimes their filtering is too effective...

Torsen from 99-02 camaro w/ 2.73 would be my choice
