67 Cuda bucket seat reupholstery help needed

Make sure the seatcovers are warm when you install them. Lay them in the sun or VERY CAREFULLY use a heat gun or hair dryer. Like described previously, "fish" around for the holes in the seat frame with a probe to line the vinyl up before making holes. Make sure all your seams are straight before securing the cover in place. A piece of steel tubing (fuel or brake line) can be sharpened by chucking up in a drill and spun against a file to make a "hole saw" for vinyl, gaskets, etc.
