Right: Sorry, thats what I meant. An option is to take the car with the trim installed. That forces the installer to remove them and mark them, so they can be placed in order. It is an absolute must that all the vynil be placed under the trim
I didn't have my front and rear window removed when I did mine. The material I butted up against all the glass edges, and used that as my mark to cut (you could see/feel the outline of the edge of the glass). It prob would be better with the glass removed (don't know) and lay the glass on top of the material: I didn't, and my top has been fine. I researched allot of sites on dif cars on the net, step by step videos, and I didnt see one where the front/rear glass had been removed first In fact it never occurred to me to do so
My big concern in putting the glass over the material would be in the tight turns at the corners. The material would tend to bunch trying to sit/form fit in the window channel, but I am sure the old school guys have figured that one out. Maybe slit the material in a fashion so it would sit flat in the tight curves
The hardest part for me was measuring and getting the material just right UNDER the rear window. Basically, you need to cut a large a fitted "hole" for the rear window
