i have found all the weatherstrips for my t-tops and door glass but have not been able to locate the continuous weaterstrip the runs along the hinge side, the bottom and the lock side of the door.
Currently no one is reproducing those parts. A good used set is about as good as you can do. Unless you have a thick wallet. I talked to Phil from Mustang II Speciality Shop in AL a couple of years ago and we quoted me $250 a door for NOS seals. I laughed and told him that I could deal with the whistle. I since found a perfect set in a parts car I got a couple of years ago. I paid a lot less for the whole car.
I searched the world, and could not find any! Luckly for me I had Mustang II doors pillled up like cord wood in my garage. Out of 7 doors I found a fair pair. Amazing what a little soap and water will do. A little crazy clue also helped
