However, if it was added at the dealership or installed by the owner it might just have
been left in the semi-gloss black e-coat that the bracket was stocked in. In the case of a
3100 side-mount they would have had to paint and replace the fender with a dimpled one
but the bracket still might have been left unpainted.

The beds were assembled at the factory complete with the fenders before the finish coat
was applied so it just seems reasonable that they would also installed the RPO's before it
went to paint.

Bottom line is it could have been body color or black e-coat and still be correct at the
time of delivery, just depends on what time frame you want to restore the truck to, that is,
factory fresh, time of delivery to the customer or a year after delivery, choice is up to
you.
