Does anyone know what the coolant temp sender hole threads in a later (1991) chevrolet v-8 head are? The earlier ones are a 3/8" NPT I think, but the newer ones are smaller and I need a plug for them.

Thanks!

The old sender is long gone and a new one just to plug it is about $25, so I was trying to find a plug first...

Are you sure the "old" heads aren't 1/2 npt and the "new" aren't 3/8 npt? Local hardware store should have what you need.
