Refitted the interior roof panels and offside panel after routing the solar panel wiring down inside the van - been on a week and no leaks from the 4x fixing bolts or the slightly larger grommet for the wire.
Got MOT (and minor service) in the next couple of weeks so also moved my Kombi bench back into the front row as I only have the middle belt when it is in the rear row position. This meant I also had to temporarily remove my B pillar table, Kombi storage unit and underseat speaker panel too.
Also need to organise a timing belt and water pump as it is 4 next month, but will use local indy for that rather than main stealer.
