I have a real 65 9" but at some time during its history the center section was replaced by one from what looks like one from the 70's. If I want to put something in there with at least 65 date casting info on it is there any identifiers I can look for to tell if something is a true 1965 Shelby/k-code center section? Alternatively, can I just put in one with the right year from any model car like a galaxy etc. if I just want to have the outward appearance of correctness? What's in there works and I have the snubber bracket but would like it more if I had at least a date coded center section for 1965 so I'm contemplating my options.
