Hello all,
I am new to this site and was hoping I may be able to get some help regarding my 70 Cutlass Supreme Conv. I have been trying to locate the chrome trim which is located on the lower rear quarter. There are actually 3 similar pieces of different lengths which run along the rocker panels, but the most rear piece I cannot find. From what I gather the piece came in either two pieces or one piece. The one piece is the one I need to replace. I was told that it is difficult to find. Any help would be appreciated. I have been trying for 2 years to find this piece, it is the only piece of chrome left on the car which is pitted and worn.

thanx,
Chris in Rhody
