Rating Gbody 9in
I recently purchased a G-Body 9in for my cutlass went with the 35 spline center and axles, disk brakes, back braced with the 1/4 wall tubes. Everything lined up perfectly and had no installation issues. Only things I would like to see in the future are possibly mounting small tabs for securing the brake lines running along the housing. But I would buy this product again or if I need another axle in the future they have my business. The customer service from quick performance has been absolutely great.

Rating 9 inch rearend
I'm very happy with this rearend, the shop had no problems installing it and everything bolted right up. the company answered all my questions when I called them and it arrived on time. I went with 3.70 gears and trac-lok clutch posi, Its a lot more fun than my old 2.73 open differential!
