1969 dart reveal kit has two clip types

The clips came from 521 Restorations. I assumed they have to be right. Is there a trick to setting the depth of the clips when drilling my holes for mounting? AlV, do you think you could snap me a couple of pictures of your clips so that I can see their placement in the window frame?

Man that's strange, it's got to make a difference otherwise why manufacture two of them. Where did you buy the clips?

As far as the holes I would drill em.
