Let me just add that if you really have your heart set on running these things the best two things you could do would be to weld a small square gusset(on on the front, one on the rear) of the leaf spring perches and also replace the "T" bolts for the leaf spring pads with quality U-bolts. These two modifications should make the perches a little stronger and prevent them from ripping off the housing tubes. If that happens, believe me, it makes a mess of things.
