Yeah I am going the, "Buy a 5mm thick steel plate and cut and mould into shape, get 5 high tensile steel bolts, drill holes through foot of handbrake assy, steel plate and floor pan, put bolts though and tighten and tack the nuts on and then weld around the steel plate to the foot of the assy and the floorpan" way
I have 2 days set aside to remove the interior, weld it up and put it all back, mainly because most of the time we will be drinking, so have desegnated that work on the car only to be done when sober
