Im not sure what my castor is but I went pretty crazy with it to see if I could miss the harness.
The engine bay method solves nothing as thats not where the wheel is rubbing, and relocating the fuse box wont help as wirse to the lights and etc must come through. You could relocate the harness to come through a higher point but that would be stupid silly work.
You guys with the plates. Do you tack them on or rivet or what?
