Throttle lever rod/spring locking mechanism broke today

[ToddXLV]

2006 XLV: The small-non heavy duty rod (that hooks to the spring) that mounts thru the circular pull up switch broke today. It's that switch that you pull up on under the chrome ball on the throttle lever. So now the throttle will not lock in at neutral.

Where can I but that specific part? Do I have to buy the whole throttle assembly? Thanks for your help.

These throttles used to come from Morse/teleflex, I would try looking them up on the internet first.
