I imagine it may have to come out again before this project is over, but for now have installed the seat box and some of the other parts. This gives an opportunity to work out what bolts are needed, and test fit whatever else needs to be adjusted.
One change has been to replace the steel fuel line with a nylon one, as I just couldn't find a way to satisfactorily brace the steel version against vibration (and hence wear and cracking, etc.). New fuel tank breather hose is also installed.
With luck the floor panels will be painted this weekend. It's starting to get cooler these days (4 degrees C this morning), but I hope there will be enough warmer days in the next few weeks to finally start to get rid of the well-worn exterior gold colour. Looks as if complete external panel painting may have to wait until next spring, although I hope not.
