Temperature Sensor Issue

I have an aftermarket intake manifold (Weiand Street Warrior) that I am running that has a 3/8 in NPT opening for where the temperature sensor goes. The temperature sensor for my year vette from Dewitts is a 1/2 in NPT. Does anyone know the resistance range of the factory temp sensor? I can probably source a 3/8" NPT temperature sensor that will work with my factory gauge with that information. Any help is appreciated. Thanks Rob.

Unfortunately, the resistance varies depending on manufacturer ... see attachment.
Doesn't mean you can't come up with something close though.
