Yup. Just throwing idea bait out on the line to see what gets a bite. A 4-bar link coilover panhard rod setup would be nice to control the rear axle, and help to eliminate axle wrap/hop especially on a light rear end truck with possibly 300+hp at the rear wheels. I know on my 56 build I will at minimum upgrade the leaf spring suspension to the best it can be. But a 4-bar coilover may be the better option, even when a complete new leak spring suspension runs close to $500.
