Does anyone have a 67 SS with a 4spd/Console and a Vintage Air Mark IV A/C unit installed? I'm wondering about the clearance between the gear shift when in 1st and 3rd gear. I'm concerned about how far forward I have to move it to clear the diffuser on the heater. If you have one installed in a 66 or 67 I would like to see a picture with the car sitting in third gear. My engine and transmission are currently sitting in the garage.
