I forgot the chrome strips that hold felt/glass rubber and not mentioned in the manual. My tip is these go on first, then triangular piece goes in. The first door i put back together i left them until last, but they were a mongrel to get back on once 1/4 glass in place. I made it happen but it involved a block of wood, a hammer and much swearing
I also found the drivers door return spring was a pain. I looped 30cm string over the hook so i could pull it over the retaining screw.
I did mine over the xmas/new year break with plenty of time. When frustrated walked away rather than force anything, was much easier than previous times in the end.
