Are you needing it for the Jetfire carburetor I assume? If so, I have some that are NOS from another model that I modify and work perfect in our cars. These are old NOS stock and are the good leather style. With me buying it and the time of modifying it I would need $55 shipped for it. I know it is expensive but I have time and money invested into them.
I have some used ones that will still work if you want to try one of them. I would want $28 shipped for it.
