Gearbox reverse switch - thread size

[martinclan]

I don't have a reverse light which is just as well as, between the removal of the engine and box 3 years ago and now, I seem to have lost the reverse light switch. I'd like to blank off the hole to stop anything getting in or out. Am I correct in thinking the thead is 3/8 UNC?

Cheers, Robin
