So like a chump, while removing butterfly and shaft from Carb #3, as I was removing the nut on the end of the shaft it twisted the shaft. Butterfly had already been removed so it is fine. This is such a precision fit I'm not even considering trying to bend it back. Posted an ad in classified section looking for a new part, don't seem to be any on ebay, and it isn't available from online parts vendors anymore.
Any suggestions?
Thanks everyone.
