I have a 70 Challenger that is a non-A/C car. I have an A/C dash and would like to get and install the factory under dash unit.
I will use a Sanden compressor and aftermarket evaporator but I want to keep the factory vent and heater controls. So, forward of the firewall is aftermarket, behind is factory.

Don't want to use and aftermarket dash unit because you lose the vents; also, some of their controls are kludgy.
And, the Classic and Vintage units only circulate air inside the car. They have no provision for taking in outside air.

Has anyone modified their firewall to install a factory A/C unit?
My first thought is that it would be easiest to weld patches on the non-A/C firewall openings and then cut the appropriate openings for the A/C box.
Other option is buying an AMD A/C firewall and sectioning the passenger's side in. This seems like way to much work. Plus it's a lot of money.

Anyone done this? What methods did you use/find best?

Thanks,
Robert
