Any experienced MOT testers/vosa on here??
After some advise if possible.
Won`t take long for the questions I have to be answered, and would rather do this via PM than on the forum.
Its to do with a ladder chassis, and removal of half, and fabrication of new replacement section.
Just after requirements, and legalities, do`s and dont`s.

Is the car already registered and on the road or does it need to be IVA'd?
As the checks for MOT are far far far less stringent than a IVA test.
From my experience with old Land Rovers, where they are frequently cut and shut; Cross members, mounting and outriggers all can be removed, moved, added and replaced, same with the main rails. All have no affect on MOT as long as its structurally sound and secure.
Structurally sound means no rust holes or cracks pretty much anywhere on the chassis or where the body mounts upon it. With uniform seam welding on any patches or replaced areas. Basically speaking as long and everything is bolted up securely (axles/hangers/trailing arms etc) and everything properly welded with no rust, it'll be fine.
Obviously if you remove or move a crossmember, you should add or re-inforce existing ones to compensate - but there is no MOT rule/reg specifically saying anything about that (except it cannot be shown to have weakend it or adversly affected handling/braking etc.), its just common sense.

They would have failed (especially the Panda) and anyway they probably should have been IVA/SVA'd
Any modification that weakend the structure is a fail. As will modifications that adversly affect handling/braking (AlfaSaab).
Now, if they locked the rear steering on the Alfa/Saab, and strengthened the panda enough, they should be able to pass (in theory at least)

But of course, seeing its the telly everyone turns a blind eye

Basically all I want to know is the bends I`m going to make and the mot etc.
Basically to make the parts that go around the wheel will need to raise up, so was going to cut a V shape out leaving the bottom of the box section alone then bending the steel to close the V and to get the box section to the required angle.
Then when the angle has been reached to seam weld the section together, and then to plate along the top to add some strength, also welding a brace.
The other thing was welding the new chassis onto the old sections, what I was going to do was fit a box section inside, then but the new up against seam welding both, then getting another section of box (6 inches long ish) and cutting in into quarters and placing the corners over the corners over the joints and seam welding that in place.
But mainly I wanted to know about the bends, as one would be near a spring hanger.
