Can anyone identify this race car panel?

I bought this piece from a local wing and rib joint with a NASCAR theme that went out of business. Most of the stuff was pictures and repro stuff but there were a few, what appears to be older sheet metal pieces from wrecked cars. I liked this piece since it wears Bobby Allison Colors and it has his number on one side, and Miller High Life on the other which was a sponsor of Bobby Allison. Its a little beat up and has 3" holes drilled in the corners. It measures about 2' x 3' and about 1/8" to 3/16" thick. The place also had a full size sprint car on a platform with a dummy engine. If this were an actual piece of a sprint or stock car, does anyone know where it might go?

It looks like a pit board, but I don't know if they were that big. What is it made of?

Its made of Aluminum.

It measures 24 inches by 32 inches.

End plates for a sprint car wing?

pit board - it would be cool to find a picture of it in use

I searched too and found the same image(s) but not one pit stall board until much later from other teams/races?????




Sure looks like it might be:

I didn't notice it originally but it's shaped like the Miller High Life label on a beer bottle, so pit board is possible. I thought the holes were there to allow roll cage tubes to passed through. They are about the same size.
