Crank pulleys will not bolt to balancer

You may also run into a small issue with the bolt pattern on the crank pulley and the vibration damper may have a slight mis-match. If you line it up correctly only one hole will be off, just make that egg shaped so the bolt can go into it and you'll be able to run the original pulleys on your car also....

Refer to this thread for more details, and ask any questions if you need to:
