Just read a comment in the Sept/Oct Issue of the Ropeshaft Reader regarding a replacement bearing for the Torquetube Propeller shaft (Ropeshaft) in the 62 and 63 models. FYI, the GM part number is 907193 and the New Departure Hyatt conversion number is Z993L05, and the newer standard conversion number is now shown as a 6005-2RS. Both the NDH Z993L05 and the 6005-2RS can be found on Ebay and various bearing suppliers. Since the specs on all these bearings show them as a "light duty" bearing, I'm guessing they don't see much of a load as used in the torque tube ( mounted in a rubber insulator) or they would have used a much stronger version of this bearing.
