Yes this forum is very helpful and I have confirmed the VIN thanks to this site. Here's the update
So lots of progress on this hunt, here's what I know now thanks to the registry and some phone calls:
67 GT 350 purchased new at Frontier Ford
Red no stripes
Vin 67200F9A02186
Purchased by my dads best friend's father David G------- for his son Steven (Steven lives here in PHX and is in a nursing home)
The car sat outside uncovered in Williamsville NY (Buffalo metro area) from nearly new to 1978.
Brought to Chicago (Hinsdale IL) to my dad's dealership on Ogden Ave for assessment, while parked in the back lot the vin tag was stolen. The car was complete at the time with original drivetrain, but it was seized and the whole car was sent to a scrap yard (minus a handful of parts which are now here in AZ)
The junk yard was possibly Victory autowreckers or another scrap yard in Villa Park on North Ave
If someone picked up that tag along the way, I can possibly get a replacement title for the car and it can be recreated. Or if someone bought that roller shell from the junk yard, I could make the parts available to them. According to the registry the car has no records of existing since it was sold new. Not in this for money so not interested in selling the parts.
If you hear of any leads on a junkyard 67 from IL let me know!
