Vintage air unit

I still haven't ruled classic out and was initially leaning toward them. I have another radio heater surround I got off ebay that is in much much better shape than the one that was in the car so I could get a set of factory heater controls and mod them for the classic. The firewall fill in is a good job and I hate to cut recut a hole for the classic bulkhead mount but I suppose I could use a vintage bulk head fitting with the classic kit just plumb the hose lines accordingly
