I installed cable scratchers on my 2016 LTX DX. Work great on the hard snow after some warmer temps. I did drill two new holes, but put them as close to the front of the skid as I could to make sure the snow would get to the track . Just place the scratcher on the rail , bend them and you can tell where the snow will spray. I made sure I could hook them into one of the openings on the skid when not using them. In low snow conditions my skid is still loaded up with snow. I usually leave them down as they won't wear when the snow is good.
