I'm installing the metal rails for my rubber trim that runs up the side of my Targa roll bar. This is the trim that the back of the door window seals against. See photo.

The rails have holes that allow some play side to side. In order to eliminate multiple tries of lining this up properly, does anyone have some guidance? The top corner needs to line up with the rubber corner of the roof seal against the top of the window.

This feels like it's going to be a lot of trial and error to install the metal strip, struggle with the rubber trim, and then find out the window doesn't seal properly.

I'm sorry, one try just won't do.

Center the trim with the holes, then slightly adjust to parrell the body shape. The if needed adjust the door glass.

Or, better yet

Install the rubber last, after installing the door, and door glass. Close the door, then adjust the trim snd install the rubber.

Comical!
