So my car blew out a frost plug during the winter and i can't find it anywhere. The parts store needs a size and i don't have a set of calipers readily available to measure the hole. Soooo...

Does anyone know the size of the frost plug on the drivers side, right behind the engine mount?

engine is a 1990 stock block 5.0

a quick response would be greatly appreciated.

Thanks guys.
