1987 dodge 4 wd truck

Any of you have a shop manual for a 1987 4 WD Dodge short bed truck? Our nephew has one and it is terribly high and he is ready to lower it. I'd like to see the manual to see what it looked like stock. I can't figure out how they raised this thing 4" in the front. I see spacers in the rear but the front looks like they swapped springs. But, they are flat, as were the stock ones, so I am not sure how they did it. Let me know if you have one that you can scan a few pages from and thank you. Tom Hand
