We went down to our injection mold department and waited until one of the machines ran out of the MSD red DuPont® Rynite material. Once the operator turned away, we filled the hopper with black material and flipped the on switch. The result is a great looking satin black cap that is supplied with our wire retainer.
The following kits were developed for the Ford front mount distributors used on the “N” series tractor from 1939 through 1952. These kits will fit the original Ford distributor part number 9N12100, and the various aftermarket replacements. They are available in a kit that utilizes the original style coil or a kit that uses an external canister style coil, which is included with the kit.
