Fender style six mounting hole humbucker base plate source

[enkindler]

At first I was annoyed with these but now I want to find a source for them for my own pickups.

They have three holes in each mounting tab which allows you to run two screws on one side and adjust the angle vs having it flop around like in the original Gibson design.

Is anyone in the 3rd party market making selling these as components?

I can drill and tap base plates but that is a lot of work and some have tabs that are too narrow.
