Broken Water Neck on my 250.. Can't find part! :(

[Isaiah92260]

I can't find the Water outlet/Flange/Filler Neck.... Which ever it's called on my straight 6! It's the part that the Temp Gauge sensor goes into, I was replacing the sensor and over tighten like a dummy, I was tourqing it down to 25 lbs and it flange cracked at 20 ..... Anyways I can't find the part on eBay, or on any of the after market websites... I looked for motor on Craig's light in my Palm Springs area and no one has it..... Does anyone on this forum know where I can find the part? Or is there a bypass part alternative that I could use? The thermostat housing keeps popping up online and that's not what I'm looking for, I don't think anyone remakes it :/ thanks for reading and helping in advance
