For my Southwest 40 I'm looking for 2 of these threaded covers which goes into the cast iron boxes where the electric wires for the lightning comes together.

Perhaps a cover from another brand will fit too. The OD of the thread is 2-5/16". Thanks.

Does somebody has this covers? Thanks.

If the size is a little bit smaller it's also OK, I can modify it a little.
