Hi,
The upper bolts pick up on two set tabs, this is a baine of the Blackbird,many bikes have rips in them as they have turned on lugs and chewed the plastic, to avoid this I used Black gorilla sealant to secure these little sods, when dry pop it back in place the sealant bonds it but does allow a little flex ,never over tighten these as if you turn them again out of their stop,,it will be repeat ,rewind.
Cheers. Be safe.
