Torsion bars for stock suspension rebuild
The reason I am rebuilding my box with a Firm Feel fast ratio internals is to get the feel a modern power steering system has.
Parking lot manuvering is a real chore with manual steering. A speed the effort to steer is not bad but it requires so much motion of the wheel you just can't move it fast enough for quick transition manuevers. There is a fast ratio manual box or a long pitman arm to spped up the steering but that will only make the parking lot manuevers that much more of a chore.
