Still Trying for the 68 rocker "spears"

I hope this link works! It is an E-Bay add for rocker mouldings that the seller claims will replace a Mopar PN 2807906 for a 68-72 Dart. They are 75 1/4" long and 3/4" wide with a triangular shape. They would obviously have to be cut shorter, but do any of you folks think they could be made to work as the "spears" coming forward from the gills of a 1968 Barracuda?

The real thing is impossible to find, and the closest thing I have so far is a CHEVY part. I think I can make it work, but the Shark is warning me about putting Chevy parts on him.

I haven't been able to find anyone locally that can show me a cross section of this PN 2807906, so I hope that someone here is familiar enough with it to give me an educated guess about whether the two pieces are close enough to try and make it work.

Thanks
