Lodola seat mounting

Another stupid question. What’s the method for fitting the front mounting bolt on a Lodola dual seat.
Does the seat cover need to be unclipped?
Many thanks,

On the advice of Brian Peck, I did away with the long single bolt and use two short bolts with Nyloc nuts. Easier to fit and the cover stays in place. Has to be done with the tanks off though.

Makes sense. Thank you.
