I’m looking at purchasing a 1967 Plymouth Belvedere GTX. The VIN currently states RS23L77. Which breakdowns as follows:
R - Plymouth Belvedere / Satellite
S – Special, 23 - 2 door hardtop
L - 440 1-4BBL 8 Cylinder "RB" engine (High Performance)
7 - 1967
7 – St. Louis, Missouri
Does the “S” indicate GTX? The owner stated the fender tag was missing. I recall hearing that the fender tag can be reproduced, is that true? I need to also follow-up with the owner to see if he has the build sheet.

Thank you in advance for your assistance!

Vinny
