i picked up a mini cheap yesterday in order to scavenge parts from it its been sat outside for a few years but has a few nice bts and the wheels alone are worth the price so today whilst stripping her ive found it has 80mm box section inner cills so if you imagine the door step and b pillar in place with no inner cill the companion bins removed and the stiffener that attaches to the heel board removed it looks like they have put a length either side running in the cavity under neath the door step so the step is sitting directly on top of the box section from front to rear
theres a closing plate welded on the end of the box section with captive nuts for the subframe
on the inside of the door step where the door seal lip is theres a 90 degree folded strip that runs front to back seam welded to the box section spot welded to the step it looks to have been done really well welding is superb tbf the floor pan is welded to the underside of the box section the only tell tale sign from outside is that the outer cill has an extra fold in it so the cill sits flat on the floor /box section i have no idea why it was done but thought i would post up for ideas i will get pics tomoz
