Just wanted to add or clarify a few points. The whole heater assembly, wiper assemblies, etc. were completely removed when I first got the car. The entire metal dash frame assembly was completely cut out and the firewall was marked up in preparation for some cutting but not actually cut yet. The stock wire harnesses were all removed and a custom fabbed harness was started with a control panel down by the shifter. Aircraft toggle switches and indicator lights were used for that assembly. Seemed like the car got to a certain point and then the modification process just stopped.
The two pics with the heater box and other parts installed were several years after I got the car when I was in the mode of assembling the car for some sort of use. I borrowed all the dash and firewall components from one of my wrecked 68 Camaros.
The rear flares were solid steel and a very strange design for back then. It was a challenge to get a tire and wheel combination large enough to fit the shape properly.
A very odd car with an unclear history. Like you said, maybe it will ring a bell with someone who is willing to share their stories about it.........
Bob, If I recall the front hubs had five lugs but they were Corvette rotors and not the OEM Firebird parts. You just can't make them out very clearly due to the feeble pics I took.
