Did all the 70 Challengers come with sill plates?

Sill plates - Yes.

Sill moldings - No.

What is the difference? I'm talking about the approximately 4" wide scuff plates.

Sill plates are located in the door jamb, 70-74 Cuda and Challenger are the same piece

Sill moldings, also called rocker moldings are obviously located on the rocker panel, these are you exterior decorative moldings

and for sh1ts and giggles, belt moldings are the moldings located on the top edge of the exterior portion of the door top and rear qtr top edge in front of the rear qtr window, the Challenger 70-1 has additional belt moldings that attach to the upper rear edge of the fender top and the rear edge of the hood, where as the Cuda only has the door/qtr belt moldings

Thanks for the info. So if my car originally came with the rocker panel moldings there would be holes for the screws.
