Bolting down the Passenger Footrest

The alloy-plate in the passenger-footwell has become an annoyance as people always seem to find a way to kick it around and wedge it under the seat so its time to fix it in place. I've been hesitating because I'm reluctant to start drilling holes and screwing through the cabin-floor in case I hit something like wiring or a fuel-line, but it turns out that floor carries on flat to the engine-firewall and the bit the slopes up for the footrest is just a thin steel false-floor.

I think it's worth noting in case I decide to remove the heavy false-floor later and completely replace it with my slimline alloy job when I decide to get the weight down. It's only held in place by 4 bolts and I don't think it stiffens the body enough for the softer metal not to work just as well. For now though I've just plonked the alloy over the top. I took one bolt out from each side of the false-floor and fixed down the alloy-plate through the existing holes with 2 more allen-head alloy bolts. I countersunk the holes in the alloy-plate, but the heads are quite deep so they only fit flush to the bumps not the plate itself.
