590474 I think Chevy, because it has a Chevy bow tie above the numbers. The other numbers I see are on the shift plate and they are (590511) I don’t know if that helps? I don’t know how to include a picture or I would. I been doing some reading here, I found that the 1947 3100 came with a 3 speed, but a 4 speed was an option. My question now is what’s a better transmission to go with 3 or 4 speed? It’s going on a 1955 235. I won’t be doing any towing, or burning rubber. Rusty Heaps you are correct sir.
