I picked up a 2009 Sportsman 850 this past weekend and wanted to put a Kolpin 2" receiver on. I have been out of the ATV game for many years and new to Polaris but seems odd the pin hole for the 1 1/4" stock receiver is top to bottom and not side to side. Is this common? I reached out to Kolpin and they said they have not heard of the pin hole being drilled top to bottom. Please help!
