DB, the frames are the same for Fleetside and Stepside. I removed the crossmember at the spring perches and will move it to the rear(as pictured). I am going to add grade 8 bolts where the rivets were and bolt a smaller "C" channel across the top of the frame rails above the perches.

This modification has been done before, check out the link.
