[trix15]

The following carrier came with my car when I bought it. I was told that it was a posi carrier for a GTO. I have attached pictures wondering if anyone can tell me what they think that I have here. There are 37 teeth on the ring gear (never came with a pinion). Ratio says 37 / 11 were for a 336, but the stamp on the ring says 37 / 9 which would be a 411, which were not a standard option for a 1969 GTO. I guess my questions are - is this actually a posi carrier? What series is it? Would I be able to reuse my 355 ring and pinion that are presently on my open carrier?

Thanks,

Blair
