correct crank (woodruff) key for stock '67 318 LA?

[ratty]

Does anyone know the actual dimensions or part #'s? About to buy a new damper (getting a Trickflow), and just in case my key is damaged, would like to order a new one too before I pull the old original damper... Seems there are both short and long and various other key differences. Thanks!
