I had the same feeling at first with these guys. Couldnt find any pictures of exactly what the mounting looked like, i called them and talked about my setup, they emailed me some pictures. Pretty sure you can get other sizes, theyre really chill and helpful. a huge deciding factor for me why I went with them was they have a badass GM type II power steering setup, exactly what I needed for my power rack and pinion. And its all excellent quality.
