I am trying to take care of every single leak on my 1965 c60. Everything is fixed besides the SM420 PTO output which ill get to eventually. This truck has the Chevrolet two speed corporate axle, the pinion oil seal has obviously been leaking for quite some time. Not to mention in the picture attached the felt washer has apparently decided to disappear. I am looking for part numbers for #3 and #4 in the picture attached. Also for my reference in the future, Do they make a book where it breaks down all these components and the part numbers that were spec'd at the time? Would be awesome to have! I've had very good luck crossing old part numbers when I can find them to new parts. Thanks everyone for your help as always. This forum has been amazing.
