  • When it absolutely must be done right, this is the place to go. Rebuilt 2 for me. 1 in my beat up 6cyl Chev trk, and 1 in my '81 Wag. 3 weeks after building it for the Chev ½t, I towed a trl 3000 miles. 1500 of them loaded with a '65 Studebaker. Not 1 problem with it.

  • Want to Thank Robert for everything he did back in April to get us on the road to get to Texas so Leonard could go to work. We had a few bumps along the way but it got fixed. Thanks again.
