Alfred, thanks so much for that picture. It really helped me. Aided by your picture, I went home last night and checked my boxes of bits and left over pieces from when we redid my car 7 or 8 years ago (the boxes that contain enough stuff from my restoration process that my wife tells me that I left enough stuff behind to make a motorcycle.) Lo and behold there were the two clips from your picture.
I hate to trouble you with this further request but would you kindly look at the piece from your picture and see if the clips are riveted onto the trim piece? Based on your picture, it sure looks to me like they are. Thanks a bunch.
