anyone know off hand what the freeze plug size is in the sides of the block in a 3.9?

I'm thinking it's 1-5/8", but not entirely sure

my guess is that is the same as a 318. but get brass ones. might be easy to just pull the engine. then you can get the back side. but the middle plug is NOT a soft plug, its the cover for the camshaft, dont remove it. edit: FEL 3818010 brass frezz plug kit.
