Help with throttle and carb linkage on 69 dart, air gap intake, holley 1850-s carb

You'll need a different throttle bracket that moves the cable further over towards the driver's side and up. You'll also need to modify the kickdown by lengthening it (you can buy a spacer) and by moving it further over (bending it and inserting it into the bellcrank from the driver's side). Also note that the throttle cable connects on the passenger side of the rod on the carb and the kickdown on the driver's side, opposite the 2bbl configuration.
