Exactly, cut out the middle, discard it, and weld the two halves back together. The first one I did took several days of measuring, layout, and prep, then a few hours of actually welding, and another day or two on finishing. That process can be seen here, although not very detailed or complete http://rides.webshots.com/album/484062061lhMQfr The next one I did took about a day total. That one can be seen here in more detail http://rides.webshots.com/album/558384968mIheUE

Also involved is figuring out the steering, be it stock or newer PS. The front springs need to be changed, have new ones made. The spring pads and u-bolt holes need attention, there are two ways to approach that, and both are covered in the picture links above. Don't forget a newer master cylinder and hopefully a booster to work with the new disc brakes. You'll see that one change leads to another, and another and another...

If you are not very comfortable with your welding skills have a professional do it. Actually both axles above I had a friend do the welding, I just set everything up, chipped slag, and wire brushed for him. Now that my welding ability has improved I will do the next one myself.

Again, this is not a swap for everyone, but if done right it is a big improvement and almost necessary if hauling much of a load at today’s speeds on the highway.
