[Spridgets] Holes in Valance '66 Sprite

[Timothy H. Collins]

Looking into the valance (or through the grill) of a '66 Sprite I see 
four - 1" holes. I know 1 on the left (which of the two?) is for the 
electrical harness and one on the right (which?) is for the hood 
release. What are the other two for? I DON'T have the extra holes for 
an oil cooler as they would all be on the left (remember, I'm looking 
into the grill when I speak of right and left for this note). I'm 
assuming those extra holes are filled with a blanking plug. Help!
Thanks
