Customs 1951 buick trim mystery??

i can not for the life of me find the gravel guards for a 51 super riviera hardtop.. i have bought all the other mouldings but this one is so elusive.. it looks like a one piece with the arch in it that rests at the bottom rocker and blends into door, correct me if im wrong, some out there has to have two laying around.. any leads would be great!!!!! attached is a 51 that has it.

 

ANYONE OUT THERE? GOTTA BE SOMEONE. I FOUND A DRIVER SIDE, ONLY NEED THE PASSENGER NOW !
