I need to know the size of the glass for a Gottlieb Premier translite for a Genesis. I have no glass to measure, but my measurements came to 20.5" x 25 1/4" x 1/8" factoring in a little extra glass for the slots. I read a post on another forum with measurements of 20" x 25" x 1/8". Just wanted to verify before I have it cut. Thanks.
