Anyone know of a recommended method to replace home gym cables if original manufacturer no longer available? Be that sending originals off to them or maybe a good site that might have old home gym stuff? I have some sort of Pacific Fitness Malibu series home gym 3 in 1 with 200lb. selectorized weight stack. Also, how do you know and how long (years) can the pulleys last? Would hate to spend 130 bucks per replaced cables to find out it isn't just the cables (which one is wavy and nylon cracked) but is also one or more (all) 6 or 7 pulleys.
