Hello. First timer here so I apologize if this is a common question. I am trying to identify some shelby valve covers my dad had in his garage. He worked at Ford motor and collected some parts for mustangs in the 60’s so I suspect thats what these may be. They are finned, painted black crinkle and say COBRA on one line and ‘Le mans’ on second line. They have twist on breathers. Inside they are marked ‘SHELBY AMERICA INC. with the number S7MS-6582. Can anyone help me with identifying these? Thanks
