Think Shackle hangers with the pins as far back as possible, without messing with some kind of additional support. They will work great in a shackle reversal too with a ramp built in, this way you won't have to spend hours and hours drilling, reinforcing, and praying that the holes in the frame are straight. Made of A50 Plate Steel and 2.0" x .25 Wall DOM. They are sold in pairs and come with bushings and sleeves. Available in 2 popular widths (OD with Bushings), 3.0" & 2.75", for 2.75", 2.5" springs. Measure your springs with the bushings installed to determine which you need.
