Yea, i know this is probably the 3rd post on Louvers i have put up and im probably annoying the heck out of people, but I had one more idea for my quest for louvers. If you look at the rear window of the 1994-2003 Mustang, it looks very similiar to the 83 T-bird. Would anyone know if the windows were close in measurements by any chance? Your help would be extremely appreciated. Thanks.
