I have a 67 but confused on my instrument bezel year. Help

[steveo3318]

Ok I have a 67 that's kind of a Frankenstein. pretty sure it has a newer wire harness because it has the side marker lamp wire but no side markers. I want to buy a new complete bezel with 8000 rpm tack and vacuum gauge. My truck has the oil pressure gauge and the ammeter gauge but no choke cable hole. My question is how can I tell if I need to buy a 67-68 kit or 69-72 dash kit? Is the wiring different in the two??? thanks guys
