I recently picked up an older chevy rearend that I think is from the 50's-early60's, and have been unable to find any information for it. From the other threads I read, it appears that there is little information on rears. Anyway, the markings are 3725899 J16 GM18 and 3725899 G99 Gm18 (I have two). The chunks remove from the front. The ring carried is marked C-30751 and is stamped ARMA STEEL. Looks like a posi unit with 11 pinion and 37 ring teeth (3.36?) I have a picture but I get a message that the file is to big to download. I will try to get pic loaded. I would appreciate any information that I can get. I'm really shocked to find so much information on the later 10 and 12 bolts but no info on the older units. Happy Holidays and thanks in advance.
