Very cool car either way but again is S1214 actually known to be a Copo # or could it perhaps be a Shop Order #?
I've read about GM execs using S/O's to get something special for their cars before, Wingate's Clippinger delivered '67 coupe is one also may be worth comparing as the tank sheet is online and it appears to be a # in the box but is too faint to see?

Info regarding the Wingate car seems to suggest it's the only '67 S/O car, maybe not?
