I shortened mine back thirty years ago. I did the tube myself and then the shaft was done at a local machine shop, it was done basically like yours. On the tube, I just shortened it and butt welded it.
Heres the funny part, I sold off the thing a few years ago when I planned on going the Camaro clip tilt wheel routeene. Now, I am going back to the stock steering and I had to buy another columm and box and I have to shorten it all over again!
