Hi
My 1969 Chevy 350 engine was rebuilt with newer heads. Head casting number 10147898 from 1995 crate engine. I am looking to add a temperature sensor on the passenger side, so I need to remove this plug. Can you tell me what tool to get? Some sort of a square drive tool. I tried inserting a socket wrench 1/4 drive and it is too little, 3/8 is too big. Is this something metric?
