The coil springs are short, about 7" from the top to the plate wich has a round base to sit on top of the differential housing, the distance from the rubber bumpstop seat to the frame is about 5", the springs can be trimmed so it doesn't look like a dragster, or maybe the base plate can be flattened and simply bolt them on top of the leaf springs.
