Are you sure it's a 7.5 not a 7.625? I think the 7.5 is Vega / Monza.
from looking at part codes recently for my car (3rd gen F body)i think a 7.5 housing would fit in a 7.625 either way.
Yeah, I used to have a new posi unit for a Monza 7.5". Pretty rare piece. But I sold it.
The g body rears are 7.5 inches. You can fit the 7.625 or 7.5 inch rear in the same housing.
I need a series II 7.5" rear LSD carrier.
Vega/Monza is a 6.5" ring gear for the lesser powered cars. In 1975 you could get a Vega/Monza with a 7.5 as an option.
7.5's are in S10's, F-bodies, and G bodies.
A 28 spline is best, if you can choose between the 26 and 28. The 26 spline LSD's are harder to find. The 28 spline axles are stronger.
My car is a 26 spline.
I have 2 rearends. One is on the car and has 3.43 gears and an LSD. I would like to put in my 2.73 rearend. The problem is it is an open rearend.
The series 3 carrier (the LSD I have) won't fit in the series 2 housing.
Anybody got an old S10 lying around and they don't want the lsd?
