Installation notes
Mount the pins to a solid point on the radiator support or slam panel, set their height so the bonnet closes flush, then mark and cut the bonnet where they pass through. Rivet the base plates over the holes. Seal or paint any cut metal. If you remove the factory catch, check that the bonnet is held securely before driving. We can fit the kit at our Mayville workshop.
