The guy that sells the kick panels on eBay is First Class Parts. The parent company is REM, and they make a lot of reproduction parts.
They are located near Hershey. I went there last fall and picked up the kick panels for my brothers P15 (wanted to save shipping), and a trunk mat for my 68 Fury. I also took the kick panels for my brothers 1950 P-19, and they made new ones and shipped them to us. And that gave them yet another pattern.
I also picked up a set of the kick panels they sold as 40/41 Plymouth for my coupe, but when I got home, they didn’t match mine (I think they were 40 only). So I sent them back, along with mine, and they made new ones of them as well.
So when they advertise 46-54, at the end of the auction they ship the correct pattern. I’m very pleased with the quality, price, and color. Lee
