Hi all, 
  
As the title, i have a 315 but was thinking of modernising it and freshening it up with a 4rt rear mudguard. I have seen pics of bikes with them on so i know its do-able, but how?? 
  
Obviously it will need to be cut down at the front, and a hole drilled for the top bolt to go through but does the rear subframe need modifying to accept the rear fastening points? 
  
Thanks for any advice!
