You can check The Driveshaft Shop. He built my old shaft in NY for my Cuda. Still works great. I found out that he is over here in NC, now. Will probably be having him build me an aluminum one this time. I have heard more than once, that guys changing over from M/S to aluminum have seen a difference.
That's funny, I have never had anybody say they saw anything on a slip going to aluminum. Always hear people saw zip. For years.
And I have heard of guys hurting aluminum driveshafts. One such guy is the guy who bought my old car.
Just like rollerized trannies. Spent all the money on one years ago, saw nothing.
