Tre3zy,
I am currently doing this delete. ill try to upload some pictures and reference my sources tomorrow. but when you see how i did it, keep in mind im not doing the "best job". some hoses are being plugged with bolts and hose clamps (low pressure lines with flywheel bolts stuffed in them and a small hose clamp). the best way is to just remove all the lines and plug your 4ws high pressure lines at your front rack (the ones going to the back, off your front rack). i am also using the -6 caps to plug my rear rack. i will retain the rear rack. also plug or change your PS reservoir, a 1G DSM works fine.
the fittings he's talking about above are:
"EARL'S Performance plumbing" "caps-6" part number: 592906ERL -

picked mine up from jegs.com
till tomorrow sir,

edit, sorry missed the 4bolt question also. here is something that can help you from vfaq.com for the 4bolt stuff.
http://vfaq.com/mods/4bolt.html im not doing a 4bolt diff so i can only help you so far.
when you take your 4ws pumpkin down. you will need to take out 7 bolts total. the 6 diff bolt + the 4ws pump bolt. its located on the driver side right next to the pump(14mm i believe maybe 12mm, will confirm tomorrow).
if you drop your mustache bolts first and let your diff hang (while the other 2-4 bolts hold the diff up), you can almost get your head up there to see it. with the mustache bracket removed and the bolts holding the diff up, youll have plenty of room to work in.
careful, i about pissed myself when the diff plunked down 3 inches, thought it was gunna smash me. i then used a screwdriver to wedge the pump loose. i found removing the diff first then work on the lines and pump.
hope this helps
