Fender Skirt ID

I was at a friends place moving some cars around to get some cars out of his shed I came across these skirts.

My friend was into Mopars but he didn't know what this would have come off of; any idea what they go on?

31" wide
4" tall in the middle of the wheel opening
3/4" thick wheel opening lip

 

They look like 52 to 54 fomoco factory skirts to me,

 

That would be my thought as well. The aftermarket ones are a lot taller, these factory ones are pretty short. I had a set on my '53 for a while.

 

don't know what mopar they fit, but i'm looking for a set for my 48 plymouth coupe
