If you pull the window trim off any Mustang (numerous earlier Ford unibodies) you will have to buy the adhesive backed foam rubber to put between the stainless steel drip rails and the car. Do not buy from Mustangs unlim/CJ Pony etc. buy from Grainger 50ft vs 12 ft. Many of the mustang people are complaining it takes 2 rolls to do the job right & they get hit with shipping 2x. For the same price and no shipping , I can do 2 cars.
