    Rated 3 out of 5 by from Quality built Fit flat, no leaks. However, the bolts included are not long enough to make contact with the threads in the diff. Had to go buy 1/2" longer bolts. Big inconvenience if you need to drive vehicle immediately.

    Rated 2 out of 5 by from So so Ordered this for a Buick Regal and had incorrect bolts. The paint is very poor quality. Shiny to thr eye, but chips by the bolt and washer pressure during install. Appears to be a paint adhesion issue as the paint is flaking off. I could have easily gotten better adhesion with a rattle can. The drain plug is also on the wrong side and "I" should have noted that prior to the purchase.
