FYI: I believe Tactical 4x4 in California is making a different air compressor mount bracket that doesn't hang down so low which would have saved you the trouble of modifying the best sliders ever made! (I have RS sliders on my Disco 3 too)
Never fear, The sliders have a bump down slider for the compressor on the original design, and I am simply having it replicated ... just in a larger dimension. I also saved the original section removed with a plasma cutter.
It can be re-attached at any time!
Thanks
