Well, busy hacking up the new front. the following show the original fixings, it may help others if you are planning on taking a front off
basically 4 juicy spots up each side of the legs/outriggers

the 2 outriggers are also welded top and bottom, one half of the box section is maybe 18g the other maybe 12g

main legs are the same all round
here the tow eye welds to the underside, note the main legs are not welded to the defo panel on the bottom

this is the rear of the n/s corner, you can see the construction method, i have unpicked the join with the defo closure part so this can be welded over the A post outer skin as per OE

new s/h panel even has a pt no
so whilst it looks a rapid job there is rather a lot of selective cutting to be done

its now sat in place

and

but

they fitted the n/s outrigger 20mm too close to the main leg! when removing the washer bottle i thought it was a bit of a tight fit, there is also a telltale additional bit of plate where this outrigger joins the innerside of the A post skin, its not an issue as no suspension is affixed to it ,and i can get some clearance for the washer bottle but it is sloppy and i can see no reason for it save forgetting to measure i suppose , im splitting hairs in a way but....
i shall leave the front for now until i have the lower panal etc aas i want to trial it all together before welding.
so will move to chopping another area out, there are a few to pick from , rear arch/s, fridge panel im easy
