I've also removed the passenger seat from the fender assembly. It's nicely shaped to re-use as the main seat for the cafe project, perhaps. I have noted that there's a metal bracket underneath the fender that gives the rear end much needed additional support. I plan to replace it with a directly welded piece between the shock mounts or a bolt-in in the first fender-support holes. If that's clear as mud, just wait for the pics to see what I mean.
IIRC, I had to add a 7mm allen key to the tool list to unbolt the seat...
