I'm looking for a rear control arm (or suspension parts) from an 1984 model. (Non-turbo.) Does anyone have one they'd like to unload? Or, alternately, is there a price you'd like to get a (slightly) used 1984 300 D? The owner is in need of parts, and may consider a sale if none available.

this site helped me buy some parts for my car. i put in your information about the car (1984 300d) and here are the parts they have by catagorty.

Thanks, 1337!

That confirms my suspicions. the car has taken it's final ride over the $1200-$1500 suspension parts.
