Harold Watkins in Morris, OK... near Okmulgee... be doing it for over 40 years that I know of! He used to advertise in a lot of magazines. Watkins Automotive I think is his shop name.
Howard in the KC area and I am sure that you could relay it to him.........I have his card around here some where and his price per stamp is a pretty good price......KCTA Chris has had a messload of work done from him.........I can look for his card.........oh wait.....found it. Hot Rod Louvers by Little Howard. 816-455-1137 I have a cell number that I can PM you.
Root, get in touch with Ross and ask him about Gasman Jack for louvers. And also, I second JK's suggestion about getting it done and coming to the Okie Twist Off!!
Harold Watkins, mentioned above is a good choice. Also a member of the HAMB in Tulsa "Doc" Parsons (that is his screen name on the board) is doing them also. J.
