I've never ordered any glass. I've always took my old glass to the local glass shops, & had it cut to the spec's of the old glass. You should be fine doing it this way. Just a note, it's not the easiest job getting that glass in. I've installed it several times, on several trucks, & it never was easy. The rubber has to be as close to correct as possible also. I've also noticed the new glass is alittle thicker, than the old glass, in my instances.
