Sorry to hear about your car, I would be chocked. Have you given Brown Brothers Ford a call? They seem to be very knowledgeable aka FGT and might be able to recommend a good body shop. Apparently the owner personally has a GT and is quite the enthusiast. Good luck
Yes, Brown Bros. Ford would be my choice to start looking for the best possible repair in the Vancouver area. I know the owner of BBF and they have done mods to my FGT. Great people and no BS. It would be worth a call or a visit.
