Shelby casting company?

[franchi]

Was there a "Shelby" casting company supplying aluminum parts to Ford? Ran across this on eBay, I don't know what it is for. I had a aluminum rear window stop that I took out of a 1965 Mustang coupe which also had this same marking. I don't believe these were cast by or for Shelby, just curious.

  No connection to SAI. Those are die cast parts and IIRC the casting company was in a city named Shelby. I might be wrong about that part but not the no connection to SAI.

I'd bet it's from this company:
