""Keys" are standard catalog parts. Any machinery supply company has them. If the keyway is enlarged, its still fixable. My brother's 240Z had the key on the crank pully go and enlarge the keyway to where the original size key would not fit well. It took about an hour with a Dremel tool to CAREFULLY grind the keyway larger on the shaft, and to file out the keyway in the pully to fit. I just took it very slow and easy until I got a tight fit to the next largest key from the machinery supply store. It was a bargain for my brother, the dealer wanted to replace the crank at a hideous price. A couple of bucks for a new (larger key) and an hour or so of my time."
