Is it possible to find the info that was on the tag? He does NOT have a pic of the tag. I know they can be reproduced but need the numbers from somewhere.
Some options: (Comments welcome).
1.) If your buddy has the Buildsheet / Broadcast sheet, that ought to have everything that the 67 fender tag would have listed on it. Not 100% sure, but that the gold standard.
2.) Start with the VIN RP23L7... and have your buddy list all the options he can recall. You can then "back into" what the Fendertag would have listed from those options: Body Color, Interior and Trim Color, etc.. Do you research about what Fendertags list for options. I don't recall how or if the Sequence number relates tp the VIN.
Discuss the theft with police - in case it's used to clone a car.
They shouldn't list your VIN as stolen, because then YOU'LL be identified as the thief if you get stopped and VIN checked.
Best of luck,
