WTB Backscatter AirLock Bulkhead Sea&Sea Type 2 (retaining nut)

Looking for a "Type 2" Sea&Sea bulkhead connector for Backscatter AirLock / Wahoo HD monitor:

This screws into the Sea&Sea housing (as opposed to the "Type 1" style which is held in by a retaining ring clip.)

Please let me know if you have one for sale.

Thank you.
