Attached is a page from the 1956 Chevrolet Truck Vehicle Information Kit for the rear suspension. Earlier vehicle data indicated length from center bolt to the ends, but not this one that I can tell. It gives overall spring length of 52 inches and a measurement of 41.52 inches labeled spring centers, but that doesn't make sense that the center bolt is only about 10 inches from one end. If only one spring had the bushings installed on the wrong end, that would put the rear axle at an angle to the frame length instead of perpendicular, so it would be pretty obvious if one spring were backwards. If both were backwards it would make the driveshaft either too short or too long with everything installed. Hope the info helps you figure it out.
