Hey Mike, so from that axle part number it looks like you need a 3k rated axle that has 74 inches between spring seats and 88 inches from hub face to hub face. The closest option we have is the Dexter axle part # T3584F-EZ-8974 which is a 3,500 lb axle that has 74 inches between spring seats and 89 inches from hub face to hub face.
