Unfortunately, only lucas parts will work. If you use anything else, you’re gonna misfire or not pass inspection. There seems to be an issue of craftsmanship that either the US part makers or Lucas screws up.

I bought the Beck/Arnley version from partsamerica and unlike the Lucas, it had a dull, rough finish and fit loosely. The Lucas part was shiny and fit like a glove.

If you plan on splashing around in the water, you may want to just buy the Lucas…Its blue, btw.

Atlantic British has the best deal for them.

As far as wires, rumor has it that the Lucas “leads” are the only wires that will work. That’s a myth. However, you cant just buy any type of wires. I’ve had success with Autolite Pro wires i bought from partsamerica.

Rover connection sells the high dollar Magnacor wires and atlantic british has the “updated” rover wires.

Napa also has a set (1756008 -> $42)
