I also had a driveshaft out of a 1970 challenger that I tried to get shortened for a dana that had a shaft inside of a shaft mounted in rubber right behind the front joint. They wanted no part of that one, built me a new one. I guess I have learned that with the with noise you describe if pinion angle is correct, a new shaft from a good shop is always the first thing to do, even if you know the balance is correct. Factory shafts are a pain in the rear, save them for 100 point restorations.
