It's been a while ago, but someone posted a review of a company from the Detroit area that was updating and refurbishing air cooled Pinz's. They raised the roof lines, fuel tank, wheels, brakes, etc. Darned if I can successfully search for that post

. Anyone with a better memory or search skills will be gratefully appreciated. Seems to me their name was Richards or Richardson and it really changed the look.
TIA
