I was ready to have my body guy do speedglass in my quarter windows but he went into the story of the speedglass blowing out of his pro street truck due to the adhesive not sticking well at all! he came up with a idea to take all of the trim off the windows and just leave the thin metal part then make the window pockets a 1/4" deeper so they would be flush and of course tighen the gap around them up also looks great however a good amount of bodywork involved. The ones your working on look great and direct replacements which is nice!
