Dusty, there really is no difference what so ever, widen, shorten, chop section whatever floats your boat.
That is the cool thing about building your truck, you can do what ever your little heart desires. You can "re-create" the truck exactly as it was made at the factory which is cool. Or you can take a saw to it and cut and weld until you have something all your own. Now, most everything you could ever imagine has been done at one time or another to one of these trucks. I have even seen one with the front sheet metal from a 71 Buick Riviera on it! So sometimes doing something JUST to be different is a disaster. But to "improve" on the design can be very gratifying. Whether or not it is actually "improving" it is of course up to the eyes of the beholder. Some can not believe someone would ever modify them at all. That is cool and to them I promise I will never, ever, chop the top on THEIR truck.
