I didn't know "the correct way to ride low is either a mustang II package or doing a subframe", and with a handle like Ole Skool Trucks I would think you would truly want to be old school.
In my opinion, the "correct" way to be old school is with a dropped axle. You can get 3" or more instantly with a dropped axle and you can remove leafs to bring it down even more. Check in the members list and find RATRODKING, he has a truck just like yours with a dropped axle. Read some of his posts for more info on what he did to lower his in the front and back.
If you just want a 2" or so drop, go with a monoleaf spring set, or remove 2 or 3 of the shorter leafs out of your front spring pack.
