The ford axle is only I believe 5/8 narrower than the Dana 35. You could also take a tape measure and see how much too
You have between the tire and spring perch. You could get spacers or a super 88 kit which would make the 8.8 factory width. Instead of a new axle You could look into a super 35 alot of guys run those with success. "
If you don't plan on going 33 to 35's the ground clearance you loose with the 8.8 is killer. I drag my 8.8 on alot of rocks sitting on 33's.
