didn't even know they made those
like you said though, whatever it take

I had a ratchet with a 13mm socket, then the 6mm star bit (bought it for a cv axle swap on a vw once)
then another 13mm also on that, then a 3 inch extension and finally the tap

it was quite the contraption
Been there done that.
Have a couple nuts welded to a bolt for removing a wierd transmission plug. Its like 5/8” hex. Ford, maybe ?
