Ok Guys What Am I Missing

[RodsGreen10]

I have looked at this so long I am at a loss.
Ok so I have installed all brand new suspension on my buddies truck everything is new front to back. New coils new spindles new upper and lower control arms new body bushings new leaf spring and new shackles. He has copied what I ha e done with mine minus the Porter front shock relocators. The issue is that the passenger side fender sits 1" lower than the drives. So I get underneath the truck and measure from the bump stops to the crossmember perch the part that the bumps top would hit. It is 1/4 different from left to right. Now I know that does not equal 1" at the fenders checked the bottom of the crossmember it is level with a laser. So I am lost I don't see how 1/4 from left to right on the bump stop to crossmember coil perch is making the front passenger fender hang down 1" lower. Yes everything is seated and installed proper and torqued to spec. So I have looked and messed with it that I just can't see anything wrong with it. That is why I am coming to you all to get your opinions. To be honest I think this is driving me crazier than it is him but my god a 1" difference is not good enough for me. Even if it isn't my truck.
