Great info; thanks 6bblgt!

But wow...that's worse than I suspected. The follow-on questions:
What's different about all these p/n?

Is there any reasonable amount of interchangeability between them?

Assuming the trim isn't NOS in the wrapper, how would you know what you're looking at if you picked it up at a swap meet?

I'm really wishing that this car were just a regular R/T!
