My son's winter car (01 Grand Prix GT) has been clunking from the rear when backing down the driveway and going over curb at the bottom of the driveway. I thought it was a bad strut but after further inspection I see that the rear right control arm (the one parallel with the car) is badly cracked and about to break. I found a used one at the local junk yard and with much elbow grease got the old one off. However one of the smaller bolts broke off. Basically there are three smaller bolts that bolt the front part of the control arm to the under side of the body. I've drilled out bolts and used taps in the past but I'm wondering if there is a better tool available now days that can save me some time. I've got the car back together now and it's drivable but don't want him to drive it with only two of the three bolts for long.
Thanks,
