I imagine a one piece bushing would fold up before sliding all the way in- the two shorties are tricky not to damage as it is. Cutting the flange off the housing, and re-welding at the proper angle and way up the shaft collar from the original face, will buy a couple of inches in the engine bay, if you need clearance for a V-8, by letting most of the box mount inside of the rail. This is not difficult but not normal welding either, as the box is a cast piece. How you chose to re-attach the flange will be a whole 'nuther discussion, as safety is paramount, among this group of builders. Many step by step accounts of this process are available, more so on the HAMB. It's a killer mod, once installed, that's for sure, just gotta do it right cause you want to keep steering! Corn head grease from John Deer is the $#!* if you don't have any of the home brews listed and need to get something- perfect for steering box and clamshell! - Chris
