Ditto what John said, we went there together when I got mine. I went to the 31's in my Ranger after I twisted off a 28 . Had new axles in about three days. They're still in the truck five-six years later doing fine. Incidently, I was on a run against the Hurricane when I broke the left axle, so it was only fair that John bought lunch!
I also went to Moser when I got the '57 rear end narrowed and had a set made for it. I've run 5000 rpm "drop the clutch" starts on slicks with those axles and still no sign of twist.
Greg Moser was a local "Hero" in Eastern Indiana until he and his wife were killed in a air accident several years ago. The son runs it now, and if anything it's better.
