New distributor to fit Vauxhall Opel cars 3 pin no vacuum or mechanical advance, also can be used for auto-grass Hill climb and track cars that do not need any advance. There are two versions of this distributor the Lucas one with the black screw down cap and the Bosch type, this is the one I am selling you can fit this one in place of the Lucas distributor, it will fit the same and is considered a better distributor.
