Alright, so I get a set of gt500 axlebacks. Of course I had to try and put them on when they came in. Taking the Roush's off was a breeze since the muffler is not as large as the gt500's. It all went pretty well until the driver side bracket, which is the side I started on. I could not get to that center bolt at all. I saw suggestions about lowering the track bar but I really don't want to mess with that. Any other suggestions for those of you who have installed it? Thanks!
