Also made some addons to my headrest. I started by making a copy of the tool they used to measure.
I got the point of the 'arbitrary' 136x53mm block when they were using this. The position is roughly where the base of your spine is when you are seated.
Standard position was just a little low,
so I wrapped a piece of wood in foam and leather and screwed it on to the bottom of the headrest. Added some fuel hose as bumpers to stop it being able to click in position too low and voila, higher than 700mm and a gap no larger than 25mm.
I also filed my side indicators and they are now greater than 2.5mm radius. Probably going to have to swap the front indicators to something else though unless I can find some 3/4 round edge rubber or something.
edit: Im going to try some of this
heavy duty heat shrink tubing. One or two layers should bring the radius at the front edge of the unit up to over 2.5mm.
