WANTED - under seat lock for "91" 851
 

hi,
the header says it all really. my seat lock decided to shear the pin that holds the barrel into the chamber as i was out riding. this must have happened just as i nailed it because the next thing i knew the pillion seat was ten foot in the air behind me. but that is when my luck changed because i stopped immediately and recovered 95% of the lock, the only thing i couldn't find is the chrome collar/ring that the barrel goes into.
so what I'm after is the under seat lock that you put the key into that pushes the pin out at the back. my bike is an "91" 851.
cheers rob
