You know what would be a great idea?
Fab up a damper system like on hatch backs, but for our cars.!
I am missing this piece as well but dont want to pull it out of the Junk yard risking messing it up so I cant install.
If you could make something like i stated that won't bind when closed i would buy in a heartbeat, so long as hardware is incuded (brakets and damper and screws/bolts)

Edit: didn't read the 98 200 part, but still if u fabbed up something for a b13 I would still buy it
