It might not be any help to you, but this picture just about shows how the chasis of my special was shortened, (not by me). A section has been cut out ahead of the spring mounting, then with the remaining rear section moved forward 6" it has been welded back in at an angle to reconect the two lengths of side member. A heavy steel plate is than welded across the bottom of all the top hat sections as reinforcement. The picture makes it look as though the insert slopes up, but that is an optical illusion.
The result is all 6'9" running gear is retained, but on a nicer preportioned 6'3" chasis.
