Missing Nut

Stupid question.....

Would anyone know the thread size of the three bolts that stick out of the upper plenum? I lost one and need to purchase another one.

Thanks

Stupid question, what does the bolt hold together, and what motor?

I believe they are m8x1.25 but not completely sure, just go to an auto parts store or home depot and take the bolt with you.they have the gauges you can check it with. make sure it was not lost in the plenum if you had it off.
