Thanks to everyone for the help, suggestions and time to look up possible sources. I finally located a NOS assembly today and the vendor assured me it will be enroute no later than tomorrow. These items seem to be almost non-existent at this time and most vendors are saying they have no u-joint assemblies in stock and no idea when or even if replacements will be available. As a side note: several sources stated there are foreign (ie Chinese) assemblies available and advised to stay far away from them because of quality issues. Just FYI
