I had Joel at The RF Connection (therfc.com) order me some BNC panel connectors with the same bolt pattern as an SO239. This allowed me to change out the connectors on my K3 and several other pieces of equipment. It is not an item he normally stocks as far as I know. I gave them the RFI part number and they ordered me 10-12 of them as I remember. They may have even have come drop ship from RFI. But RFI wouldn't even acknowledge an email from me. The RFI part number is RFB-115-14 if you want them to order some for you.
