What are the big and little hole in the filler panel for?

Do I want to weld in patches for these since I have a custom radiator/support setup?

Sorry if I seem ignorant. But, I didn't take this car apart and I haven't found any diagrams for this.

I believe these are drain holes..the big one for the rad petcock and the small one so water doesnt get trapped/ rust out under the rad:)

holes?

I don't know what the little hole is for but I yhink the big hole was nfor radiator drain. You could put a section of hose on the end of the petcock and run the hose thru the hole and not have anyi-freeze all over the front of your car.

I think mike's reply is correct, the little one is just so water doesn't puddle there when it rains or snows.

I just found this in the assembly manual.

It looks like the little hole is for a hose that connects to the petcock. So, what is the big hole for?

Is it for the radiator overflow hose like 1956SD says? It seems kind of big for that.

The big hole is for 6 cyl. drain. The hole is larger because the petcock is too close to the filler panel to turn without the large hole.
Weld 'em up.

The small hole (in center) is for the center brace that goes underneath . I think mine had a rivet there.
