What size key for my crankshaft?
I have a 1995 Oldsmobile 88 Royale. How do I find out what size the key is for the crankshaft? I know it's gm part 12563282 and I need to change my harmonic balancer, but can't until I can get this key which didn't come with my balancer.
No where can I find the size of the key. Could you measure the one that is in the car now?
