Kijiji Find "NOT MINE" Dodge Demon Gss 340 4spd Tri Power Numbers Matching

This is a real GSS and one of the most highly documented, since it had paperwork not only from Grand Spaulding but also from the original owner that he had kept. I spoke with the original owners son a couple of years ago when I tried to make a deal with him.
The car is obviously not 100% correct as a 71 340 Demon should be but it's also not quite correct as a 71 GSS either. There are a few items that are missing from original. I am also not sure where he comes up with his one of 8, ever, one of the 2(?) four speeds... one highly touted 4 speed GSS isn't even real. No one knows the total production on these but since there are 8 or so that I can account for now, I'm sure there were a few more.
This car has gone up in price $30k since I was dealing on it. Yes, it's the same one that was at BJ. I'm pretty sure the guy selling it bought it since it only bid to $38k.
These are extremely rare cars but the knowledge out there on them is slim. If anyone has any questions please contact me.
