I put the wagon springs on my 66 years ago, and it raised it too much (for me). I recall it was at least a couple of inches. The convertible springs that rickm suggested may be better. I put Air Lift bags in my stock springs, plumbed separately with the valves behind the license plate so I can stagger the air for wheel hop or add air if I am going to carry around some of my more rotund buddies. The bags last a few or more years and one will crack, so then you buy another set and replace them one at a time.
