On mine I used aluminum strips about 1in wide. I ordered a book through Mancini and it has all the measurements from the original SuperStock Cars. You don't need the book to figure it out though. The Glass has two holes at the bottom where you can attach the Brackets. I found some rubber grommets kinda like what you would put in a Valve cover for a PCV valve and put them in the glass and ran the bolts through them. I also used Nyloc Nuts so I didn't have to crank down the bolts to tight on the glass. Once you have that figured out, run your brakets down and drill some holes behind your rear door panel and bolt them up.
