My Dart Swinger Project!
I took all three of them apart the other day and it was amazing to me how much better the quality of the 71 was. The 71 has metal around all the gauges and separating the bulbs the 75 was masking tape and cardboard I don't recall what year the spare was out of 72 or 73 it has the seat belt light but not the egr whatever year that was, but it had the cardboard spacer too
