Heater Input Fitting By Distributor

[BAD0MEN]

Hello, the fitting by the distributor on the intake where the water comes out and goes to the heater broke off in head. I need to know the tap size for the hole

so i can put new threads into it to put a new fitting in. I have a 1995 Silverado 350 5.7 engine. Any help appreciated.

You can buy a regular nipple from the auto parts store to replace it but that's going to be one big a$$ tap if it's the fitting I'm thinking about. You might end up replacing that manifold before it's over.

Here, I'll answer my own question It is 1/2 inch npt. The tap and drill bit to do the job cost me 11 dollars.
