I probably missed your email... take a look in my FAQ, it goes into detail about the differences between the premium and ultimate. Basically the premium is printed a a backlit paper similar to emdkay, and the ultimate is printed on a true backlit film like a translite/oem marquee.
I typically leave .1/2"-3/4" on the top and bottom of the marquee free of graphics for the retainer. There is a comment section when ordering, you can just give me the total height and viewable height and I can take it from there.
