I will do my homework about ss springs, don’t know about them yet. My plan was when i will be relocating my springs instead of drilling a hole on a frame take the existing bracket and weld it under the frame, it will give it another 3 inches lift, what i was told.
For the front not sure yet, i called the other day local junk yard, they said $350 for a complete strait axle from an A100 dodge van, and i do love how gassers look, but looks too high to me, maybe dropped straight axle? Like 3 inch drop?
