if its a track car im assuming its a v8. i ask because the slant six is a rod and the v8 is a cable. im converting my valiant to a cable using a lokar throttle cable and universal gas pedal, im even using the lokar kickdown cable to keep everything the same. the nice thing about this setup is you can mount the pedal assy. anywhere on the firewall that you want. i have not mounted mine yet, but 64dartwagon has one and i saw a valiant in a mopar magazine a while back with the same setup, so i know it can work. you can also buy a universal gas pedal from summit that looks just like the lokar but less expensive. good luck
