Needed to call the company to find out the equivalent and they directed me towards MRO. If this one will last as long as its predecessor I'll be retired by the time it will need to be replaced again. - Gear box - excellent service, fast, easy, and customer service outstanding, if any changes they call and let you know, - Coach - Timely delivery in an untimely world.
