thanks C. how did u hold the top part down then? with tape?

and i figured out the size. Just went from small to big in a piece of wood and tested the grommet in each size. It will go into some small holes but when i pulled it out...it cracked. So i went bigger and found a good size. 19/64 works good. Grommet wont pop in unless good pressure is applied so im sure it wont pop out. And when it does come out it doesnt brake.

I kinda like no door caps...gives it more a sleeker look, imo. But who knows...i might change my mind.

One more question....if i buy aftermarket skirts...will there gromments be spaced like stock ones so i dont gotta drill new holes?
