M25 is 69-71 body sill moldings, nothing to suggest wide. To my knowledge 67 dart GT came with a wide sill moulding, a 68 GTS sill moldings were an option and 69 GTS they were standard equipment. I believe on a 68 fender tag it will show if they were chosen. 69 as standard equipment not shown on fender tag. Again 69 GTS would come standard equipped with wheel opening moldings along with sill moldings at no additional cost.(included in the GTS package). Hope this helps.
