anyone know where to find new ones? I'm talking about the trim piece the joins side rub rail & the rear , I was thinking of having them made out of billet, but I would like to get my hands on a spare set, I wonder if you could even purchase them from AO?

That sure does look like a special piece. I too wondered where these would come from if needed.

Mine are a cast alum. I had mine off for a sand blast and a repaint. There were no numbers or names on the back side at all. Looks like a special made piece to me.

mine are made from fiberglass, & painted, but they get nicked real easy, I would love to find an pair made of aluminum

Mine are made from the same material. I did ask Jim on where he purchased those rear corner pieces. Damn if I can remember where he said his supplier was located. Sorry.
