* The person you bought it from couldn't provide a name who he bought it from?
* Do the motor reciepts have a recognizable signature? Perhaps you could call the machine shop.
* Any participant decals have the track name/location that was attended? You could go to Div. 3 national/divisional qualifying sheets on
www.dragracecentral.com and look for '72 Buick GS qualifiers to sort through. Maybe try some NHRA Div. 4 races also from back then.
* Find some Buick forums. They are a tight group and could help. Tom Rix is a long time Buick racer who ran in IHRA Top Stock. But I have no idea how to get hold of him or where he lives.
* This search shows a pic of a yellow Buick from 1994-1997, but it's a dead link.
