RUN- - - -do not walk away from that overpriced, overseas-made distributor. Find an OEM distributor on Ebay or in a salvage yard, and rebuild it with a "new old stock" module and pickup coil, and make sure the centrifugal and vacuum advance systems are in good shape. You'll spend less money, and have a better, more reliable distributor. Ditto on the Bosch type relay and heavy current wire. I use a 60 amp capacity relay, mostly because the wire gauge in the stub harness that comes with it is heavier than the 30 amp version.
