Dart GTS Custom sill moldings question

My 69 GTS currently has no sill molding.
I know the pencil style sill molding was standard on the GTS, but my fender tag is stamped "M25" which I beleive translates to "custom sill moldings".
Before I search for them, I would like to know exactly what it looks like.
Im thinking it is a wider molding than the standard thinner type.
Does anyone know or have these?
Thanks
Joe
