Be advised that the sensors are held in place with three tiny nuts on
studs. Given their environment and the fact that they leak, it's quite common
for those nuts to be rusted solid to the studs, which are just brazed to the
radiator tank. If you don't take appropriate precautions ahead of time,
when you try to remove the nut, you'll break the stud off. So be sure to use
plenty of anti-rust penetrant and let it soak before trying to remove the
nuts, if there is even a hint of corrosion there.

(They're listed at $25 each on Wilkinson's site)
Presuming that's true, it would be far cheaper to just replace the sensor
with a new one of the same style, rather than going through the trouble of
having the radiator modified to accept screw-in sensors.
Dennis Quella sells a bolt-on adapter machined out of aluminum, which lets
you screw a conventional sensor into the stock location. It's a bit
expensive though, and if cost is the only factor, then you're way better off just
buying a stock sensor.
