Detailed Description

This Pioneer Cables throttle cable is engineered for direct replacement use where a carburetor accelerator cable is specified. The CA-8421 part number is built to OE dimensions and materials, making it a practical choice for restoring throttle linkage operation on carbureted vehicles such as Ford Mustang and Chevrolet Camaro applications that use this cable style. This part cross-references AMS Automotive 4116 for the same application.
