As far as I know the 1-8 fender tag codes are molding codes
G and F are for accessory groups/ package, lines 35 and 36 on IBM card.
529 - Wide sill molding
535 - drip rail
Body side Belt molding is code 540 on 1968 Dart, as stated above
541 - Licence plate frame
542 - door edge guards
543 - door upper
544 - sill molding
545 - body side molding
546 -
547 - B pillar molding
548 - wheel lip molding
549 -
649 Delete moldings is on 68 broadcast sheet - this could be what 8-9 is as it is a pretty rare coding from what I can find. If this is a dart 270 it would have come with body side moldings with 270 on rear trim piece. Code 649 c/would delete this molding and it is not seen on your car. If you have the broadcast sheet under rear seat bottom normally but not always. If you look at the molding codes IF 649 has a 9 in the box it is a delete molding code.
Bumper guards would be a 1-2 or 3 ending code for codes 481-2 or 3 as stated above.
These codes are from 1968 broadcast sheet and 1968 ordering codes for 68 Dart and 67 IBM card (I don't have a 68 IBM card to compare to) direct from Chrysler Corp not a decoder.
Thanks Rocky and Dave. I looked into the code for belt moldings, it is 30. 89 could be the bumper guards. F0 comes up as Decor Package on some decoders, so maybe F1 refers to some option package.
