69 dart GTS decode !

I was thinking that too. If it was a W25 it should be after the V codes. Probably they guy punching the plate used the W thinking it was an M.....although I don't see any wide sill moldings on the car in the photo.
Couple questions sir seeing you seem to know your way around codes? I have an M25 wide sill moldings in my fender tag but for the life of me I have no idea what that description refers to? Secondly where would one find a code that states car came with fenderwell/rocker panel moldings? My car is a 69 GTS and I have no idea whether they were stock from the factory with the GTS option or if they would have had to be ordered?
