Cool! That is a neat way to add weight-bearing without resorting to trial and error. I think Ben already has a line on the Ranger springs, and I've heard of that before, but if a person ever got into such a situation when converting a car to an EV, it's just another idea to use. You'd just need mounting bits that were the same, and extend/retract lengths that were close, and you'd have a chance to really impress someone with all the talk about your "custom" suspension!
