Aftermarket radiator question

Just bought a new radiator for the old 91 Corsica. It has a place for the low coolant sensor to plug into but it requires drilling to open up. Any ideas on what size this is? I would assume it has to be exact, as the sensor is directly inserted into the radiator and only has two small seals to keep fluid from leaking. My GM manual says diddly quat about it, and only briefly mentions it anywhere. Has anyone done this before? Is there a better way to do it? I do not see how this would seal well in the first place, but that is the way it was designed.

Well, if anyone buys a new radiator, be sure you take care of the low coolant sensor installation before installing the radiator. I did not notice that the new radiator was not drilled for the sensor, looked like it was, but was not. I was able to use a 1/4" bit and drill thru and then install the new sensor and connect. A pain in the rear since it was partially blocked. Would have been easier done on the bench.
