Simple interior treatment minimizes weight but keeps the driver informed. The stock accelerator pedal and linkage use a complicated system of rods and bellcranks that require massive reworking with Hyper-Pak intake. Instead, we used a '67-up A-body hanging-pedal unit. Position it where it fits best, drill four holes in the firewall, and tighten the studs. An accelerator cable from a 2.2 minivan connects the gas pedal to the carburetor. A little grease on inner workings of the reverse-pattern push-button gear selector (left of the steering wheel) restores smooth operation. Proper shift-cable adjustment is best made with the transmission pan removed and a helper. Have one person fully depress the neutral button while the other turns the adjuster wheel at the transmission case. When the shift detent lever aligns perfectly with the neutral safety switch, you've got it. The MSD ignition mounts to the firewall. The brown wire must be snipped for six-cylinder operation.
