One of the things about seeing 68s on the field is that you normally only get to see the dash VIN and the underhood fender tag. I should have been more diligent about seeking out 68 warranty tags before posting.
In the world of 67s different states have different views on how to deal with what to call these cars. Some list the cars as FORD or MSTG (or some variant) mine says it's a SHLBY.
Considering there is a dash VIN (Fed required) what does the title say?
I think this is still in the '68 Shelby VIN' lane.
