So I have been reading many post on this topic and I have gotten a lot of conflicting information.

I am planning to change out my 95 F150's 8.8 axle with a 10.25 sterling. I have read this should be a direct swap for the springs perches. I know my current wheels will not fit and I am ok with that too. The area I am getting conflicting information on is the driveshaft and Ujoint. I have read the driveshaft will need to shortened to it should be fine as is. The Ujoints are the other area of confusion some say they are fine some say I need to modify different parts. Can someone who knows this swap help me out?
