What interior kit to use?

My advice is check them out before you buy. Our '69 seat skins are not rolled between the pleat lines and the back seat basket weave strip is about an inch narrower than the originals. These were supposed to be PUI and we bought them about 4 years ago. The quality and fit were excellent but the finish was not exact. Today could be a totally different story as people are starting to insist of things being absolutely correct, as they should be. If your old skins have minor problems, many times a good upholstery man can do excellent repairs that you won't even see.
