I got a ck30 with the kioti cab on it and I'm wondering if there is another option for installing a wiper motor for the rear glass. My rear glass doesn't have the holes for the wiper motor, therefor I would have to buy a whole new rear glass for $300 plus the wiper motor kit for another $300 from Kioti. Im not to keen on spending that much money just for a rear wiper. Any ideas? Thanks
