As stated earlier in the thread, Nash Truck Parts (a local establishment) rebuilt and re-sized the rear drive shaft. Dropping in the automatic and NP205 made the original too long-so they corrected the length. They also reconditioned the front drive shaft, but did not reassemble it (at our request) so it'd be easier to paint. He sent us home with a new non-greasable Spicer centering yoke (or socket yoke assembly), part number 211544x. The Spicer greasable one which should be a direct replacement is 211355X. You can see the difference between non-greasable unit and the original. Dimensionally they were nearly the same. But the socket diameter was wider than the original which caused a problem. We could get the double cardan together but it wouldn't straighten out. The width prevented it from seating fully. A Moog 607 centering yoke was available from Advance over night that had the same profile as the original. I picked it up this morning and we were able to get the driveshafts together and in today. We also installed the metal vacuum line for the transmission and the kick down cable brackets in preparation for mating the cab.
