When I re chassis'ed Noel, I used a Richards chassis (👍👍👍)
And replaced all bushes, engine and gearbox mounts , brake pipes, clips/brackets etc with new.
As above, fit with no washers. And don't tighten. Then add washers when your are doing the alignment. You can cut a chunk out of the washers, so that they are U shaped spacers instead. Saves you taking the bolt out ....
Had to adjust just about every single item.
Never, ever fit anything tight. Roof, side frames, tubs, wings bulkheads etc before checking everything lines up.
We live and learn 🤔🙄
