I didn't see anything in my searches of the site using the search feature. Is there any information on how to identify an original vs a reproduction 1967 GT500 air cleaner? 1/26/67 build date. Thanks

It should be a diecast lid and base. Repros are sand cast. The lid has a particular style of letters and also a faint witness line around the letters. The quick and easy way to tell is look at the bottom side of the lid and there should be mold filling injection indentions about the size of a pencil eraser around the perimeter of where the filter sits. The base is easy in that it has strengthening ribs cast into the bottom side and also a S7MS engineering number to identify it . No repros like that . The base also has a swedged in PCV 1/4 circle shaped nipple that will turn with some persuasion.

 I wanted to clarify that the air cleaner assembly for your cars production date would typically be diecast . In that context I wrote my response. There are earlier production 67 GT500's that used a sand cast lid and base from the assemblyline  however those assemblyline sand cast assemblies are also substantially different to the repro counterpart as well.
