Wheel locks for 7/16 20 left handed thread 13/16 lug

Over the last several days, I have scoured the internet looking for wheel locks for my 68 Dart left handed thread 7/16 20 thread and 13/16 lug. Nada!
Any ideas where I can find some?

I know I should swap out the studs for right handed threads and live normally but too many moving parts for my to do list for this year.
