Trim assembly in

[steplift20]

it looks like the head of the bolt broke off and since i got the part as used the mech is not responsible for the out come but i was looking at it and it looks like it should be fine, its the bolt that goes in to the trim rod area the other two that go in the housing are in solid and since its all one piece they should hold fine but im want to always get a secound or thied opinion and you guys are them cause if i knew 1/3 as much as you do i would be a master mechanic
thanks
