So before fully thinking it through, I removed this nut and cleaned up the cut.
This way the fuel tank basket can ge hung and secured.
Then reconsidered all the options and decided the pie cut and forcefully bending the diagonal into position before welding it in place.
Pie cut welded up and ground back, right next to the original welds.
I needed to be a bit clever with the diagonals footplate.
The floor is corrugated so I decided to create a stepped plate.
Plate made up to match the original support.
Welded in place with bolts and spacers in place.
Ground back.
And result.
Hoping that mate @paulf makes it here tomorrow evening to visit, check progress and deliver his hydraulic press for the bushes.
Road trip Saturday.
