1970 Water Pump housing freeze plug

[erik70rt]

Does anyone have a good pic of the type of freeze plug that is used on the top of the water pump housing for a 1970 383?  The previous owner installed an aftermarket temp sending unit and I pulled it out last night.  Now I need the freeze plug to fill the hole on the housing. 

Thanks!

There is no freeze plug in the water pump of a big block Mopar....

Maybe he meant the normal threaded plug?

Yea I believe he's talking about the threaded plug. The correct ones are hard to find with an inverted 1/2 square hole.

Yes, that's what I meant.
