I sold mine. Got them at Fresno Airparts for $28 each but they need a little extra machining before they will work with the new style harnesses.

I have the die to cut the proper size threads on the cups. The existing threads need to be filed down a little for the die to work.

The threads on the cups are correct. They are different than the sparkplug threads. If I know we are going to use cups, I send the nuts to Skytronics for them to be installed, otherwise I have to take the harness apart to checnge the nuts. The size I believe if the same as the SF4 or Eismann mags with individual leads

Re: Shield Cups for spark plugs

I sent my old wires to them requesting that they use the connectors on the old leads. This was discussed with them. The new wires came with the spark plug thread vs. the cup thread. It wasn't that big of a job to change the thread on the cup.
