Howdy all! I am looking to replace the rear axles in my 72 Skylark. After looking at several brands and their statements my head Hurts. Is anyone better than the other? Who did you use and how was the product and service. 8.5 10 bolt with bolt in axles. I plan on chaning the ratio to a 3.08 from the 2.56 in it now with some posi unit so I may have to change the spline count. Thanks Mark S.
