I have a dumb question, but can seem to find an answer to it. Got a 1977 olds 350 crank that I lost the crank key from. I was going to order another, but it doesn't seem right. Dorman is calling for a 1/4" x 2 55/64" straight key, but the keyway in the crank says different. That key would be to long and the side closest to the motor looks like it was cut for a woodruff key. What am I missing?

Sounds like the right size to me.

It's a straight key. The radius at the rear end of the slot is just a manufacturing expediency. That slot is cut with a circular cutter. The straight key just stops before the radius starts.
