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. - Grove gear - ordered it got a week early was exact to the specs performed flawlessly - Gearbox gold - Great Gearbox, great price, free shipping!
