here ya go.. this worked very well for my CT. You may find you need to use more than one washer (I did)
First loosen the right side shock fastener, then remove the right side end of frame fwd rail bolt, put washer/washers in place and replace and loosely tighten the fwd rail bolt. then tighten the shock bolt. Finally finish tightening the fwd rail bolt. This causes the rear bolt/nut to pull the fender out away from the tire a bit.
