Shown
above is an intact right side 687-02UA piece.
We
sell these either intact as above; a "UA" piece, or those
with one peg broken; a "UB" piece. Two or more broken
pegs and we discard them or give them away. We used to
remove these and put some fine mesh screen material over
the plastic defroster nozzle and then put this back in
place. These are a terribly poor desgn. They break easily
and don't stop much. They tend to fade to a light grey
color eventually. I repainted mine black with model
paint.
