I have just completed my body lift on my 00'.
here's some tips for you: If you dont have a torch and an impact, use pb blaster on the cab and bed bolts... LOTS of it..
also, my bumpers didnt want to fit back right, so you might have a little trouble with them , esp. the rear... just follow directions, use commone sense, and measure EVERYTHING.. and you'll be fine.. I actually enjoyed my lift...
