I may have mentioned this before. Contact each and every person owning such a car (Including Series 75/90) in the Directory, and see if they have a spare to sell. Please remember that only 1% or fewer CLC members regularly use this message board, and would know of your quest. If you ask for "one" from many of the members, you will have a much better chance to find "two" of them if you need a pair. And, one of the happy results will be that you will find many new friends. And if you find them for sale, you will find them pricey, generally. If you are offered one for fifty dollars, or in that area, rejoice. If offered one for less than that, they are treating you with the utmost charity for a fellow car owner, and you should offer the most profuse thanks possible. When you are looking for something like this that is hard to find, you can't just put a request up and expect to find one without expending some effort yourself. You may even find someone who will send one to you gratis. (Hey, it's how I got my RH "washboard" for my 60S...)
