Modern dually wheels have a LOT more backspacing than the old iron, so consider what wheels you're going to use and if adapters will be needed so the thickness of those is factored in, to decide whether or not a particular front end is going to work.
Try looking at 3/4 ton/1 ton single wheel setups vs. dually as well. Obviously your wheel choice will play a role here too.
