Hey all, so I am told from a family member that the rear under my 54 6100 came out of a 1973 c60. It is a two speed vacuum actuated rear. I haven't been able to find any serial number on it. I was about 10 (quarter century ago) when my grandfather took it all apart, rebuilt it, and put it under the truck as a replacement for the original rear. The brakes were never finished being hooked up, and the lines are in bad shape, it has almost no miles on it since it was placed under the truck. I am looking for any information I can to confirm that it is indeed the rear I am told (pictures would be wonderful), manuals or documents regarding the brakes, fluids, service, etc. As always your wisdom and "knowledge transfer" are greatly appreciated. Thanks!
