How has everyone else mounted theirs? The Tilton website says to use an M8 fastener and a large washer but surely the floor pan will flex on an Escort?

I was thinking about stitch welding two 6mm thick bars (similar to the files I've sat it on) to the floor and bolting the box to this, or is that a bit overkill.

Also, the pedals need to be vertical when depressed, so angled toward the driver when not pressed. Is that right?
