What do the clips inside the trim look like? I'm assuming they have the sharp pointy bit that gets hammered through the plastic things. Could you use a different style of clips, maybe one that has a threaded fastener?

There arenít any clips on the trim side. These have a lip that slides on the trim and then pushes into the body. Same holes as your 68. What do your clips look like? I found these and ordered some, might get them today. If they fit, Iíll order more(need 32 total). They measure darn close, just missing the metal support. Plus the few I salvaged are 53 years old and fit a little loose. Thanks!
67 and 68 sound the same, just donít know if they are the same size. The ones I bought are too big. As I try to modify them, the outer lip that keeps it attached to the trim is ground off, thus rendering unusable. Iíll keep looking!
