Ignition switch REALLY hard to turn now!

the ignitions they sell at the parts store are a little off, had to change the one in our dart the day we got it and it came out ok, went most of the way back in good too. that last 1/4 inch was a pain. don't know if it was the column or not. the ignition was messed up when we got it. a half hour job turned into two hours.
