I sorted this out by cutting a bending block to the radius I wanted clamped it to the van then started hitting very hard with a really big hammer, this didn't quite work as I had hoped.
So I had to make a couple of strategic cuts with the angle grinder then start hitting it again really hard.
With the help of the gas torch I finally managed the bend I needed
Then welded up the gaps
Ground the welds down then hid the welding with some red oxide paint
With one side done I get to start on the other side.
With a little less disregard than the first time I cut the van up. I dug out the electric saw I had for cutting my hedge down, It took me 2 min to pull the support out.
Then cleaned up the surface of the spot welds so I could see where to drill them off.
With the old support out the way I can mark the cutting angles I need.
