I have a 1999 mustang GT. I bought the car with a B&M hammer shifter in it. This past week the little lever you pull up on to push the shifter forward to go into reverse and park broke. There used to be tension when I pulled up on the lever but now I pull it up and it just falls down. I'm not able to put the car in park or reverse therefore I am not even able to take out the keys. Do I just replace the shifter or is it just a part I need to fix?
