Oil pressure sensor?

[Chevlowrider]

Im just about to fire up my 5.3 for the first time but i need to wrap up some details first. i need to get the right fitting to put my old oil pressure sensor into the new motor. does anyone know the exact fitting i need? otherwise all i really need to know is what is the size of the hole in a 2002 5.3 for the sensor so i can find the fitting?

drill and tap the old 5.3 pressure switch. break the top plastic conn take the guts out and drill it and tap it works great and saves money

i dont have the factory pressure switch for the 5.3 so cant even go off of that to figure it out.

I suggest just drill and tap the oil cooler blockoff plate...easy. Im sorry I cant remember the thread pattern or size though.
