I met the owner of Vintage Air near SA yesterday afternoon. They build absolutely top-of-the-line A/C systems for rods, customs, and muscle cars. He toured me around the shop after hours and showed me some parts from the F-GT. It turns out they are the OEM supplier for your cars. They are also beginning some work for an upcoming McLaren-Mercedes model, so you know they are good!
The owner is a certified car nut, with a particular penchant for 32 Fords and vintage Indycars. His latest hobby in the design stage is a 32 with mid-50's Indycar running gear powered by an early Dodge F.I. Hemi. TOO COOL!
