Its on a engine stand, and I'm trying to replace the crankshaft. When I bought the car it had a OBX underdrive on it. I put a OEM crank pulley on it, but the damage was already done. Two weeks ago the oem pulley developed a slight wobble. Back when I put the OEM pulley on, I noticed the keyway in the crankshaft was messed up from the underdrive pulley. I found the original keyway today when I pulled the timing belt cover off. Right now I am jut hoping the motor will be ok. Thanks for TSRM link, scanning it now for info...
