I have just received a rotor arm and distributor cap from Europarts (I am now waiting for them to get back to me). They sent the wrong parts. I ordered both parts by Bosch, alas they have sent me a Bosch rotor arm and a Bremi distributor cap. So while I am waiting for them to ring me I thought I would ask if any members know if the items could be used together even though they are from a different manufacturer?
I've had exactly the same thing in the past. All I can say is they did both work together although I'm inclined to believe it isnt an ideal combination.
