The transmission casting date appears to be L-12-??, and I can't tell if the VIN is factory since it's out of focus, but from what I CAN see, it appears like it may just be a typo on the POP. But having a mid February transmission in a late June car is very strange! Especially a Saginaw.

Yeah I'm not sure what's going on with this transmission. Still haven't been able to find the transmission code on the body yet but the VIN I can make out is 455013 which matches the body, engine, and POP. Don't have a better picture on my phone right now unfortunately.
I suppose if I can locate the stamp on the transmission and the code is identical apart from the S at the beginning then that could point towards dealer error?
