I've found a trans code, but have no idea where to find the list of RPO codes. Thanks.

All the codes are listed on the inside of the glove box lid.

That was fast. I was just getting ready to run another search. Thanks a lot.

On my father's 1991, they are located on the inner part of the panel at covers the spare tire.

On third gens they can be found on the glove box lid or under the spare tire cover.
