Throttle and Kickdown Linkage
It's a standard 273/904 with a factory 2 barrel kickdown setup modified to fit a 4 barrel. No pic at the moment but it is just a factory 273 kickdown from an early a body (the solid bar coming off the carb to a steel plate mounted on the rear of the motor). Modification is possible but if I can find something close that requires minimal mods that's a plus
