I agree with 52Carl.
Considering that you’re already questioning the quality of the bodywork that’s already done, you need to fit it to a frame. You’ll have so much structure already gone that you’ll need those fixed points to have any chance of getting it right. I would also weld some supports across the inside of the door to keep the door opening from moving.
Once you get the supports positioned correctly, you can remove the cab to complete the welding.
You definitely have your work cut out for you. Keep us informed and post any questions you have.
"Work cut out for me" sounds like an underestimate for sure! Thanks to everyone so far for the good ideas to get me back on track. Today got away from me, but plan to have a look at what has been suggested. Jay
