question for the Mopar gurus, I was at a show yesterday and a local guy as a 1968 GTX 440 hardtop, car is clean and appears complete with correct 150 mph speedo and buckets.

what I noticed is the VIN tag on the dash which was FRS23L8A 237xxx, I took a picture of the tag but prefer not to post without owners permission. Car also had its matching fender tag and the correct RS23L8A237xxx without the F

VIN tag as the correct fonts , Chrysler logo and rosette rivets, to my knowledge appears original as dash shows a few resprays and tag was not properly masked and shows , I just dont know why VIN starts with an F and as a total of 14 digits.

Owner was telling me it was du for European export, which I dont believe...

Could Chrysler have mande a misprint?
anyone else ever see a F or an idea ?
