nc23 fairing question.
 

Hello , I am working on 88 nc23 in the US , and can't figure out something on the stock fairing with bat wings. In the area where the front fairing and the bat wing side fairing come together there is a part of the front fairing that has a 1/2 circle section that looks like it bolts to the radiator bracket but I can't find it in the shop manual. Is there anything out there that will show me what attached to this section of the front fairing?
