Install a key
I'm inclined to agree.

Does anyone happen to have the part number for this key?

Hey man, I ended up having someone else finish the job because I ran out of time to complete it.

Nothing wrong with that. Glad your car is back on the road.

Thanks brother. It didn't fix the vibration, but improved it slightly.

It doesn't seem like it's a driveshaft issue, but I'm going to remove it and have it balanced with new u-joints anyway.
