Item # 123JAG-6-R-V with vacuum advance. Click here for installation instructions.The ignition-system in a classic car is often the source of many problems. After many years the mechanical system is worn, and replacement of the points with an optical or magnetical setup, does not make up for wear in the advance-mechanism, the shaft and bearings etc.Well, 123ignition is different. It comes in a housing, that exactly looks like its mechanical counterpart on the outside, but that houses a lot of high-tech on the inside.A 123ignition keeps the looks under the bonnet 'original', but makes the engine spin like a Japanese sewing-machine Moreover : you don't have to sacrifice your mechanical distributor.
