So I purchased a set of these running boards this fall. I'm a little hesitant to install them still. Any tips or suggestions on how to get it done easily for those who have installed a set before. Im nervous about cutting my sled up and dont want to make any mistakes. I have installed better boards before. But these are a bit more involved. It seems like the plastic grippers can be replaced by some metal screws for better traction. Any advice is welcome.
