Three bolts on the bottom of the differential will do the drain job. I think I can get some new cly for the rear OES 35.00 each You may need the adjuster pinnions also I think I can still get those too.
I have a 1946 Chevrolet 2T that looks better that the day it rolledout of show room. As for other information you may need drop me a note and I can copy any service information you may need. I am an retired Chev dealer. During the 40's and 50's worked in Service Alwayys willing to help. Going sout for the winter so can't help much after Jan 1st
