Adding an aftermarket temp gauge

I want to replace the over-temp light sender with the sender from my new temp gauge. Can someone tell me what size that fitting for the factory sender is? I need something to screw the new sender into.

It's either 3/8" or 1/2" NPT. I'm basing this off some literature I'm finding online for the gauge I installed. I know it came with the correct adapter, but I can't remember which one I used.

how are the readings back there though? maybe that spot doesn't read an overall average uniformed reading?

LOL @ chevyeater,

Thats not the first time I've seen you recomend that location, then stating since it was shown it will probably not be used...

I really don't think the coolant temp readings anywhere in the block are going to be significant, but to be sure after the discussion we had last on this recently I ran my truck into town and back and hit each bung with the infrared gun, I got a pretty steady 192 out of the rear port and the front was floating between 191.6 to 192.3.

Then I installed an old SW mechanical gauge in the rear port. Right now I'm just setting down after running her 250 miles up and down some serious grades, from 500 ft, to several high elevations up to 3,200 feet at Buckhorn summit. Then down to sea level then back up to Oregon through the redwoods. That new engine/tranny kick butt! Anyway, I was impressed to see how accurate the factory gauge really is, cold (180ish) is on the low side of normal, 190-200 around the center, 210 is as hot as I got and the factory gauge was just right of center.
