I will add ARO to the list. They claim to be the original convertible top manufacturer for the Mustang. Here are the things I checked for with my top order: All of the suppliers have the Ford White top material and the black material. Zipper: Brass zipper, most open from the driver's side. You will need to add the leather pull "tang" to the zipper handle. It's just heavy duty boot shoe lace or baseball glove lacing leather. If you have the snap in your last bow you need to order the strap for it. Most snaps are in the middle of the bow, if not, tell the suppler. Rear curtain: if you don't have state inspections can you order the plastic window without the imprints? (Hoping for the day when someone comes along with a stamp for the proper concours imprint) Tacking strip: NPD sells the correct one with the stainless steel end pieces and screws. Make sure you cut the tacking strip to the proper length. I think I remember that NPD sells it in 72" length. The Ford Assembly manual has the proper length. A common mistake I have seen at shows is that the installer made it too short. Lastly, in comparing all of the major top suppliers to my original top, when I bought the top for my second Mustang, I did not find anyone who made it with the correct edge binding. My original top has a different vinyl pattern on the side edge binding, the rear curtain edge binding, and the front weather strip/ roll-up. No matter which one you order, the installer is key to a good appearance.
