Size of woodruff key on Crankshaft?

[K5german]

I will have to re-cut the woodruff key seat into the crankshaft, it got all torn up and I am filling the old one. Any ideas how I can find out the size? The old seat is totally ruined.
I can't find this info in the manuals anywhere?
I don't have the time or money to pull the engine out to swap the crankshaft, so I'll remove the radiator and plan on filling the old key seat and the re-cut it. I want to get a proper cutter so anyone know the woodruff key no.?

Thanks

Oh, also, while we're at it. Where can I get the seal, bolt and washer. They all went flying!!! The harmonic balancer got wedged in the radiator and tangled in all the belts (thank god) so I still have it.

Thanks for your help!

You can get the seal from any auto parts store. Bolt #14022672 and key #106751 are available from GM. The washer #14022673 is not coming up but part # may have changed.
