67 Dart 273 timing issue

I can move it to two positions. First, to the 4:00 position as before. Or second, I can move it to the 7:00 position. The end of the distributor is flat and fits into a slit that is five sided. The five sided part slides into the cam. I cannot point the distributor toward the first drivers side intake bolt. I can freely turn the gear once I pop it up with a screw driver.
