Help ID 273-4 valve covers

So what do I have here? Notice the lack of wire loom bracket for the PCV valve cover? I figured it went on the driver side and stovepipe went on passenger......it looks like it never had a bracket, no bends or old welds on the inside where it was tacked on....


Could they have swapped sides for the pcv/oil fill for one year? Either 64 or 65?


It does look like yours are original.
