these guys rebuild and make peg leggers into posi's my brother inlaw went though them a few times now and they have been great to work with i do not have a number they are out of Tayler MI company called Rider Racing Greg
www.reiderracing.com You also may want to contact www.drivetrainspecialists.com they are also located here in southeast MI. My brother and I had our 12 bolt built at Reider and they did a nice job but they are a little slow about getting parts. It seemed like we could get parts delivered to us before they could get them. Something to consider. They both are highly respected around here.
