We needed a distributor for a '64½ Mustang with a D-code 289 4V engine. Garrett Marks at Mustangs Etc. pulled this core from his inventory. It's a C4AF-12127-U single-point Autolite distributor, exactly what we need for a daily driver. Garrett was also able to provide us with the correct B8QH-12120-A bushing to complement our rebuild. PerTronix set us up with an Ignitor II module, a Flamethrower ignition coil, and ignition wires for improved driveability.
