Last time I was at Tosey's They had a couple of sets there. I just looked for there phone # and can't find it, I'll check when I get home tonight must be in the home PC.
Just a guess, but I have to believe that Sanderson sales has a but load of them sitting around, or at least one complete set for every fastback they have Eleanorized.
Since I'm building a Shelby clone, I sold mine on ebay. They didn't get much ($40 if I remember right) and they were perfect. Might want to check ebay and use that info as a guide for how much to pay.
