Markings on Differential 69 RR

[SgtLee511]

I'm curious to know if this B is significant to B bodies, or is it the initial of someone checking it off, I have another one in the garage with a Big C. The other pic probably marking the fluids checked? Do yall have any photos of other Tramp Stamps, on your differentials. Im wanting to reduplicate these markings, I also noticed yellow on the case towards the spring pad, but I was not able to identify it.

Depends on the plant, the inspectors both factory and manufacturer. If I did not find it on my car I left it off. I enter into judged competitions which I do and say I copied marks off the internet for my Lynch Rd. built car go to a show and a judge sees the same markings on my car as a St. Louise car and he has photo documentation of it being proper in St. Louis. But that is just me I take it to serious I guess. Ok I'll lighten up now
