Might want to obtain paperwork from PHS on the car - might not be the only one made, but could be close to that.
I have the paperwork.
PHS may have a few counts on the ultra-rare, like Trans Am ragtops or 1971 Judge ragtops, but they don't have production numbers as a whole except for engines and transmissions. Until missing paperwork pops up, there will be no way for me to know how many built. I do agree it's quite a rare piece.
This is my friend's car. It has the 428 HO, 4-speed, 4.11 gears from the factory. It's a strange one. Mine doesn't compare.
