Ok, that was completely unhelpful. But honestly, you are trying to move a mountain with a sandcastle shovel.
Look at J Demello's
truck. That is the kind of fabrication you are looking at to do it right.
You will need new axles front and rear (and huge gears)
You will need to box the frame.
You will need a new engine and transmission.
You will need a new transfer case... and maybe a second transfer case.
You will need new steering components.
You will need to be an expert welder and be willing to spend at least $15,000-$20,000 and a lot of time.
If you do it any cheaper, you will break something everytime you go out.
Best Luck. I recommend starting with something a little more robust from the get go (consider a used military blazer or deuce.5) It will be much cheaper and infinitely easier.
