Looking for a source for reproductions of the rear bumperettes for 70-71 Cuda.......or possible good used of same.If pricey has anybody came up with a tasteful way to block/mask the holes in the rear valence? Also looking for good reproducer of the door sill plates as all i've found so far is NOS at $109 cdn each in aluminum. I'd really like stainless if they're out there.
