the important things for me were: making sure the bellypan and control arm brackets were properly installed (measure and measure again so its not mounted at an angle) and when your putting in your control arms, make sure to measure them out equally like said in the instructions.
for the control arm brackets it says to take a hole saw to put the little plate in the unibody rails for the two bolts to bolt up to. i just took an angle grinder and cut out a rectangle shaped tab, folded it down, mounted the brackets then folded the tab back and welded it back into place.
upper control arms were a pain in the ass to get off, so i just cut them as close to the body as i could and left them there for the time being.
make sure to have a sawzal and some nice metal cutting blades, you will use a few cutting the original lower control arm mounts off.
i just completed my lift not too long ago with a friend, so its still fresh in my mind. if you have any questions PM me or something, ill try to give you advice the best i can. i see your from ohio, where in ohio are you from? i could let you borrow my instructions, they are a bit dirty though haha.
