Fender Tag Codes???

That was one of the sites I used. There are some indentations on the radiator support, but my primer and paint work filled the numbers in to the point where I can't read them. Are there any other places for those numbers. Anyway, I have a few other interesting things to mention. The Motor numbers match the VIN tag, and the automatic tranny (before I converted to a 4 speed) matched the VIN also. That really throws a wrench in the works. If something fishy was going on, why would the engine and tranny match the VIN? I don't really care, because I modified the car a lot. I am just really confused.
