Hard to describe it. The oil pan will be sort of a long rectangle with a side that juts out on the drivers side.
Not many of those codes mean much to me.
D 29 should be April 29
73 CJ 18109 looks like a good number but I can't decode it. My guess would be 1973. CJ I'm not sure of. 18109 is a sequential number.
Most trannys have the RPO code cast in them starting with a M. Usually larger letters and hard to miss.
Try looking for the VIN number. The VIN on a TH400 is stamped on a machined surface just above the pan on the drivers side. This can tell you what car it was originally in when it came from the factory but I think the numbers on the tag are all you're going to find.
Most of those other numbers are likely casting numbers, date casting codes and assembly date codes.
