I had a friend of mine shorten and weld mine. He actually ground off the old weld and pulled the yoke from the end of the tube. He shortened it, and reinserted the yoke then welded it up. It turned out great. Hes been welding all types of metals for the past 25 years and I trust him far better then I would myself.
One thing I would be sure to do is index it so the yoke can be put on correctly to be in sync with the other u-joints.
I never had mine balanced, he did an awesome job, and I have no vibration at speeds of 50+mph.
