This is an original Bosch distributor rebuilt by an independent specialist. (Bosch no longer makes or rebuilds these themselves.) It is the correct single vacuum advance distributor for your engine, with the proper advance curve (unlike an 009 style centifugal-advance distributor). As a result your engine timing will be correct both at idle AND under load, which maximizes engine lifespan, performance, and gas mileage. Basically it's better for your engine, and performs better as well.
Note: We charge a $20 core charge, which is not reflected in the price below. Your core charge will be refunded after your core is determined to be acceptable. If it isn't in acceptable condition, your core will be forfeit. Contact us for a final invoice, or checkout and a supplemental bill will be sent for the core charge
