I know that Carey Hines at Special Edition/Beck now does all his bodies in-house in Indiana.
Greg at Vintage Motorcars does coupes, Speedsters, and Spyder bodies in-house at his new shop in Hawaiian Gardens.
I'm pretty sure Henry at Intermeccanica up in Vancouver is an in-house guy too.
JPS and "new" Vintage in AZ are unknown. Did I miss anything?
