Did I do ok on this?

Since you were ok departing with your money for the car, it is OK!
was it worth it to you? don't second guess your decision now, what's done is done! Go scratch that itch! :thumbsup:
This is exactly it right here.

Sadly there is no fender tag.i wish I had it!.i do think I over paid but I don't mind.according to the local mopar guys,I have the only 2nd gen fastback in the area!
Look on the drivers door jamb on the body in the middle near the hinges. The VIN is there. You may find out some information there. While no fender rag, it may shed some light.
