Just being lazy... 67 Dart GT rocker trim measurements

Anyone have their 67 Dart GT rocker trim off?

I'm looking for a few dimensions.

1. Diameter of the holes in the body the clips go into

The hole diameter ( I think is 1/4 maybe 3/8") I would have to pull off a quarter trim to measure and would rather not disturb the trim made from Unobtanium if I don't have to.

Thanks in advance
