1969 Barracuda Dash Help

I'd still have to go with my first assessment. A sill moulding, is typically a door sill moulding. Either way. Id buy a new one, and mask and paint the black. Your 2 other dead giveaways its a sport package is the 383 engine it was equipped with. This is in the vin, and the R/H muffler bracket mount plate shown in your interior pic. Sport package cars came with dual exhaust.
