Okay so I was trying to install my steeda underdrive pullies tonight on my 2000 GT and everything was going good until I got to the crank pully. The bolt for the crank pully came right off but when i tried using the pully puller it will not come off for anything. We were wrenching at it for like 3 hours and it still wont budge. Does anyone have any suggestions for what i can do to get this pully off? Now my car is out of commision until I can get this off. What should I be carefull of doing so not to damage the crank?
