I sell these new for $22.  It is not that hard to change yourself.  Just
start in the middle of the van.  Cut the old cable and attach the new cable
to it (aluminum tape, wire, be creative).  Now pull it toward the back, now
pull it toward the front.  Adjust everything up, and you are done.  Takes
30min-1 hour at the most.  Hope this helps.

Thanks,
Ken Wilford
