Grrrr! Water temp adapter... Well, I have now broken two coolant plug adapters, one an autometer and the second was one I made out of the stock plug. The autometer adapter will not fit the stewart warner sender, the SW sender is too big. 
I drilled it out and tapped it, but it broke while threading into the head, not enough meat and strength in the thin walls of brass. Helluva lot of fun getting it back out. Tried making a new adapter using the stock plug which worked great until I smacked it installing my headers. Broke that one too. 
I was just wondering if anyone had the part number for the plug? 
I'd like to try and grab a new one tomorrow. Getting close to starting the thing up now.

I'd like to try and grab a new one tomorrow. Getting close to starting the thing up now. I broke one of the autometer ones too... Next time I went to autozone I ordered two of them...just in case. On the next install, I took the "crush washer", and put a thin film of rtv on both sides. I tightened it just enough to squeeze the rtv out and get the fitting tight. Then I left it alone. I wasnt about to try to crank on that thing.
I think autometer could provide a little better sealing washer for that piece. Maybe something with an rtv ring already on it. Mine is easy enough to get to though so if it gives me trouble Ill figure something else out.

I used the Eqqus adapters..... broke my first one just putting the sender into it before twisting it into the head..... I was a lot gentler with the second one...... but I still keep an eye on that area for leaks 'cause I don't trust things I can't over torque!

Thought about retapping the hole but the engines in the car and it has A/C now... would have been a lot of work. Drilled and tapped a bolt today. We'll see if it holds pressure tomorrow. The bolt killed a drill bit and a tap.
