I received this distributor off a forum member roughly a year ago. At the time i was trying to find a distributor to clear my boss intake and blower drive. The cap was too tall for me and i have since sucked it up and bought another unit with a crab cap. Mallory does sell a kit to convert this over. New they sell from $160 I'll let this go for $100 you pay shipping. Item located in Whitewater, WI 53190.
