Hi! I'm new to the forum. I have a RadRunner that I bought for my teen daughter's Summer job commute and I ordered a RadWagon 4 for Fall delivery. I am trying to install the front rack on the RadRunner and have hit a snag. The light mount that came with the rack has smaller holes than the original light mount. The bolt won't fit through and I'm not able to enlarge the holes. Has anyone else experienced this?
