Hi i bought some racing rear sets from the bike shop for my mc21. i went to put them on and realised that there is no hole in the brake leaver to mount the bracket for the tail light. does anyone know an easy way to fabricate one or another way to hook it up without drilling a hole through the lever.

Also the at the rear of the lever where it is mounted to the cylinder the small pin wont fit through the hole. would it be best to just drill out the a little or is there a smaller sized pin that i just havnt got... The rearsets look quite similar to the tyga ones if that helps at all... thanks
