I have a 2002 Ranger. After several attempts at checking and replacing the vacuum lines leading to the control valve (even though the old ones still looked good), as well as cleaning the valve, I gave up and bought a new one when the same old codes kept popping up.

While I was installing the part, however, I somehow managed to drop the bolt which attaches this part to the engine, and of COURSE it bounced around several times and conveniently hid itself somewhere on the frame or elsewhere. I spent 20 minutes searching and could not find it

SO my question is, as I don't have a stockpile of metric fasteners around my garage, can anyone tell me the size (diam and length) of this bolt?

THANKS!!
