I still need to drill for the ac and heater connections, fill small bolt holes and support the evap case under the dash by welding elevator bolts to the firewall.

Yeah, I should have stayed with the perfectly good factory system.

Hi Doug,

Any chance you'd like to sell the firewall cover plate that came with the Vintage Air kit? I'm doing the same thing with welded studs inside for a smooth firewall. I'm doing the bodywork now and they're estimating January delivery for the kit. I called them direct but they don't offer a digital or paper template, the firewall cover it's self is the only method they have for locating the 1/4-20 mounting bolts.
