I have a 96 Mystique V6 5 speed and i had my drive shaft explode on my yesterday pulling out of the parking lot at work it poped my ball joint right off the nuckle the only thing that stoped my car was my tire smashing in to my fender .....my question is that the bolt going throught the ball joint has a tourx bit on it and the other side has a 17mm bolt going throught it witch one is the proper one?? and if it is the tourx bit dose any one know what size it is cause i dont have one that fits it and i will need to buy one oh and sorry about the spelling

Thanks alot..... Paul
