Dropping the radiator 1" is probably the most involved part. You can remove the radiator lower brackets and redrill the holes 1" lower. The hardest part is redrilling the upper mount. You have to drill a new hole 1" lower on the body. Not to bad though.
The fan is obviously part of the engine which rests on the frame rails and does not move, while the radiator is bolted to the body and moves up with it. You won't have a fan or fan shroud left if you don't address this issue. You can also cut the bottom of the fan shroud off, but I worried about how close it was to the hoses on the bottom of the radiator and decided to relocate the radiator down 1" like others have done. I didn't have to mess with the T-case and tranny linkage, but some do encounter this problem.
Corroded body mount bolts and nuts can be a problem, and make sure you don't jack the vehicle up under the rockers. I recommend some wood underneath the driver and passenger feet rest areas...nice and flat surface to jack up. And don't over do it on the jack up part because you can stretch stuff i.e. brake lines, heater hoses, etc. It is not that hard of a job man, and it is a great mod for very little $$$. I am convinced if you deflare and high clearance the fenders and run a 1" body lift, you could easily run 37's with the stock suspension! Easily...
