I think most of the good guys are either not with us anymore or getting ready to not do that kind of work anymore. I think what you need is a place that pretty much only restores certain cars. Example, for us a place that does Fords and will do research to do the car correct. Can you imagine a Mustang trunk in that spackel paint that GM uses?
Maybe a forum post that asks, Shop recommendation in your area? I know where I go in New York, but I am not there anymore, I have no idea where to go for anything where I am now. Perhaps, ship a car up to my guy in NY?
