No offense dude, but a body drop is a pretty invovled thing to try to tackle. I've seen your other treads (I mean this in the nicest way possible, for real.) I dont think you ready to do this. Think about it, you could render your truck useless in a matter of hours if you dont know what your doing.
I do have some pics of my truck (521), which is body dropped. But i wasnt the one who body dropped, although i wish i would have been. I'm ashamed to even put the pics up of that though. I guess it would be a good "what not to do" haha!
Good luck man.
BTW, i mono-leafed my nissan hardbody a few years ago. If you deside to go that route, i recommend the old school air shock method. You shouldnt really use them to support the full weight of you truck but if you just use them to give you a little lift out of driveways, speed bumps, etc. It should be ok. And they are pretty cheap. like $80 if i remember right. But remember you are going to bottom out on EVERYTHING and it will ride like crap.
