Nothing worse than a nice car with those NASTY plastic A/C outlets!
When I was re-doing the '56 Nomad -- I found a pair of perfect OEM A/C outlets... IIRC I paid about $500 for the pair at a swap meet. Nobody made repops back then.
The problem was - the compound curves - and I wasn't exactly certain of their location. Since the car was painted - I wasn't about to just hack away and rework an area... So lucky for me - I found a dash from a '56 A/C, and get this, also factory PADDED!! I've never seen one (padded) in a car. I bought the whole dash - and then I could make a pattern from that and cut my dash, and they fit perfectly. I still have that dash... for no other reason than I've never seen one.
I'd also made a "console" out of wood and bondo and metal.... because I loved to drive that car and needed a cup holder!!! LOL
