Gift for Mopar people

A lifelong friend of mine really went the extra mile and did me a solid favor. I'd like to give him a gift of some kind. He's a lifelong Mopar guy, and has plenty of diecast and other stuff like that. He still has his first car, a beater '75 Dart 4door with a nice little 318 under the hood.

What's a good gift for him?
All suggestions are appreciated.
Thanks
JOS
