Same ones are on my '78 23' but I still have to cut off half of the inside flange both front & rear in order to fit [img]/images/graemlins/frown.gif[/img]
Insead of going the Awlgrip route I lightly scuffed them with a red pad and wiped with "Liquid Sandpaper" and a couple of coats of the new "Krylon Fusion" spray just for plastics. Thay had a color that matched my trim. It seems to hold up pretty good [img]/images/graemlins/wink.gif[/img]
