I had the same mentality when wanting a body lift, go big or go home right?. I ordered up a Roger Brown 3" Body lift with new poly bushings (nice product). But after doing some more research I decided to cut it down to a 2". I'm glad I did.
With the 2" BL, I had to cut out the bottom of the fan shroud (i could have lowered the entire rad housing but cutting it was much less work and from what I have read, there is minimal impact on engine cooling). The brake lines that run down to the frame were fine since there was a lot of play left in them (as the were coiled, i just had to bend them a bit longer). I had to make the 4L/H shifter opening about 2 inches wider at the 4H, 4L positions but didnt have to touch the main shifter. While you get an increase in shifter throw, the main shifter itself got shorter which i actually prefer now. I wasnt able to loosen up the steering shaft as the clamp was seized, but it didnt matter in the end since the rack and pininon accepted the lift angle just fine. I find the space between the front bumper and the body unremarkable and find the space at the back bumber asthetically acceptable.
If I had gone with a 3" lift I would have had to extend the clutch hose for sure, widen the shifter housing even more, fabricate a new shifter boot, lower the fan shroud instead of cutting it, raise the front and rear bumper... a lot of work for an extra inch... but thats just my opinion.
Ive wheeled it pretty hard and havent noticed any shifting in the body at all. But there is a lot to be said for replacing those poly bushings and retorquing with new hardware. Also making sure that the body mounts at the frame and the body have intact metal is important. (I went to the extent of cleaning the metal of rust and rust painting them a these locations before installing).
The 2 " lift gives you enough room between the body and frame to really clean it well in the winter and get at it if you want to rust paint it.
hope this helps
