Admittedly I did not carefully read the details here but once I had an odd noise coming from the driveline of my 1952 Henney-Packard which had just had the transmission rebuilt. Typically I do my own work of that nature but that one time there was a rush and, as I was living in an apartment with only a carport, I deferred to a nearby shop. It turned out that they had put the clutch plate in upside down (or backwards, depending on how you look at it) so that its little springs were lightly touching the flywheel bolt heads! Put in the proper direction, the noise was gone!
