f-150 springs are a good swap if you want to lengthen your wheelbase. the centre pin is offset. but i dont believe they are a direct swap. if you want a cheep lift. look for some lift shackles. keep them at about 1-2 inches longer then stock. that will give you about 1/2"-1" of lift. look for an old set of cheep lift leaf packs. or someones old lift thats worn out. mix and match. maybe an add-a-leaf. getting your springs re-arched can work temporarlily, but the spring will be shorter eye-eye, and it will sag sooner. keep the body lift for the last thing to try. good-luck;)
