54 inches is the most popular top stack size. 60 inches puts you right at 13.6 and you may have to cut the stack at the bottom to be under 13.6. a 64 inch top is over 13.6. If you measure from the center of your top clamp up to the top of your existing stack, that will tell you what size you need. Thanks!
