Harmonic balancer
 

I couldn't get mine off the car and it ended up breaking. Can i use one off a gran prix, lesabre, or regal since they have the 3.8 to?:confused:

Nope. Different 3.8 motor.

haha howd u break it? you shoulda got a puller

Even with a puller if you don't use it right you can seperate the dampners pretty easily. Make sure you are grabbing the inside of the dampner instead of the outside ring.
