M20 oil pan to chassis ground bolt size?!?

[bassboy3313]

Hey guys! I am finishing up the wiring stuff on an m20 turbo swap into my e21, but cannot for the life of me figure out the bolt size/pitch for where the chassis to oil pan ground cable bolts to the oil pan. Anybody know off the top of their head or can measure it for me? I have checked realoem with no luck and also have tried multiple sizes of bolts from hardware store with no luck. I must be doing something wrong, lol.

Help quick, please!!!

What about the thread pitch?

Just to be clear, its the bolt hole right next to the oil pan sending unit I am talking about
