Carb rebuild question

[bumt72]

Ok the carb on Da BUMT needs to be rebuilt, so I went down, purchased the rebuild kit, pulled it off and was about to tear into it when I noticed a plastic part on the choke assembly was broken, and wasn't part of the rebuild parts. The question I have is how do I get a new one, what do I ask for, do I have to purchase a complete choke kit to get it etc. etc. etc. The carb is a stock Motor Craft 2bbl

Here is a picture of the carb for reference



Here are two pictures of the part I am talking about, the red arrow points to it.



Thanks

Junkyard or a carb shop. If not I might have one here.
