Sounds like a “jump ball” for now.
Don't even think it's gotten that far
Just a possibility and something that has bugged me since the early 80's. What always got me was that even way back then none of the examples locally were hot rodded in any way and one would think that if someone was building a fake and as a convertible someone would have installed headers, aftermarket wheels, an after market radio, factory colors ..... something other than as they would have been built if they built any. Especially way back then. Just didn't/doesn't seem to fit the idea that these were all home made by multiple people. Was playing with Mustangs at the time but came from a drag racing, customizing, and restoring older cars background
Maybe one day one will pop back up - they had to go somewhere
