Those are engine side pans. The close the area between the engine and the frame at about where the pan bolts to the bottom of the crankcase. There might be brackets on your front cross member and back near the front of the clutch housing.

This is the passenger side pan on my 38. You can see the road draft tube dropping through it. They are side specific.

Ok, i will look. But i didn‘t see any brackets

There may not be "brackets" as such. Look for matching holes in adjoining sheet metal and on the frame rails.

Thats the Problem, cant find any matching holes

I mentioned the brackets because it is not unusual for them to be left behind when the pans are removed. Maybe another owner of a '40 will come along and straighten us out.

I have a project truck that claims to be a 1940 KC 1/2 ton, built in December of 1939. It has an earlier bed on it, so its originality is in question. 

But, in case it helps, I have attached a few photos of the engine side pans on my project.

The first photo is of the passenger's side and the other two are of the driver's side. Let me know if you need specific angles and I will post more photos.
