Just had a set of original 1967 tags restored by this guy >
http://www.restoreatag.com/
I run them mounted on the car all the time now, with the actual registered tags in the car windows when driving it on the street. Get to the shows, put them away.
The tags came out unbeleiveable ! 1000 times better than new. Pics dont do them justice. This fit, finish, shine and quality is as good as the paint on my car. After talking with this guy, come to find out, he does all the work for Jay Leno, Has done work for Seinfeld, and just inked a deal with Kounts Customs to do a few TV shows with them. He gets and does tags from all over the world.
The owner Shawn, just taped a show with Leno and will be on a tribute show to him in the comming weeks, featuring Leno's cars and the guys that restore them for him.
All I can say, is if your looking for restored tags or anything that he restores listed on his website, this is the guy ! Hes not the cheapest, but when you want quality, this is the guy !
