(sorry if there's a more relveant thread, feel free to merge)
I've long ago lost the LHS rubber thingy which hold the front rhs bottom corner of the LHS sidecase.... but I just use the RHS case on a daily basis for lock/cover/shopping/packed-lunch
I recently removed the RHS pannier for a day and guess what.. I lost the RHS rubber thingy.
so I cut 2 rings (5cm wide) in the tube I had left from the cush drive mod, wrapped one twice around the metal bit attacked to the peg, then wrapped over the 2nd ring twice and pronto !
I'll see if I can get a picture
