66Dvert,
The pics are a good help. The ruler next to it would not be necessary because the spacing of the holes in the rocker panel and the width of the molding itself pretty much dictate dimensions. Looks like there are metal fingers that go through the rocker panel holes and expand as with many other clips. Thanks for posting the pics.
AussieDart,
The pain must be double, being so far from the original parts, such as they are (or aren't).
I'll be spending some time figgerin' out a way to make my own clips. That sounds a bit challenging.
