Get some scale valve stems and just drill on into the wheel. The wire can be made using thin gauge wire and coiling it by wrapping it around a needle or pin.
From what I have read, only one Dodge and one Plymouth ran a 4 Speed and that was Dave Strickler in a Dodge and Butch Leal in a Plymouth, The rest where 727 equipped cars.
I have on in my stash and it is a really weird little deal. I think it was normally a Monza Funny with the addition of the nose piece to make it more "Carter" like.
Very cool! I am surprised there are not that many pics of this car out there. Plenty of the Fuel Altered and the Funny Car, but the fuel car, not so much.
