For ChrisC! Sorry its taken a bit of time - managed to find pictures from the actual build.........they're not great, but give a decent idea for the crutch straps. Lap Straps: Inline with this picture - using existing belt point on outer side, using exhaust cavity, in line with opposite fixing point: Positioning with trim in place: Crutch Straps - only on drivers side. As mentioned before, one of the fixing points is going to be slap bang where the fuel lines run, so they'll need to be disconnected, and protected - but here's the fixing positions that I had used in relation to the placement of the ktec bases - as I sit in the seat now, they are directly in line with the base of my spine. http://www.schroth.com/installation-instructions/en/index.html Cheers
