Chrome 1970 340 Valve Covers....Hustle Stuff Direct Connection or Factory?

I have these chrome 1970-71 340 valve covers, they have the wire loom brackets on them....my question is are these vintage Hustle Stuff or Direct Connection parts? Did these ever come stock on an cars, possibly the AAR or T/A? Or maybe someone had the stock ones chrome plated? It’s vintage chrome and looks like it’s original to me but I’m not sure I’ve seen these before (Sorry I haven’t cleaned them up yet so they are a little dirty) Any input would be great, thanks!
