I need some help identifing the two pieces of molding I have attached. Both the seller and myself thought these belonged to a 57 Roadmaster 2-door. The measurement along the top of the radius is 28-3/4". This is 1" longer than what is on my vehicle. Can anyone help me figure out what these actually belong to. And if anybody needs them let me know I will be happy to sell or swap for the correct pieces.
