Here in this listing I have a set of 6 screw in distributor cap spark plug wire retainers. There is a brand new insulator or wire separator disk included as well. These are in fantastic condition with no damage to any of the threaded parts. A great set to have to secure a tight connection to the distributor cap. Here is your chance to get a set of original screw on wire retainers for your classic car. Please see my other XK120 parts I have listed as well as the tools this week. Thank you for your interest. I am offering FREE postage for United States buyers on this item and all international buyers will need to pay for the first class postage to their destination.
