My coupe has a GM rear end that I think is from the mid 50's. It has the casting no 3725899 on it. Any one here know what model(s) this is from or where I can find out?

Thanks, Jim

I was able to i.d. mine at a wrecking yard. They have a book. Mine was ,at that time a 1957 truck rear end. It is now a 88 Camaro.
