I'm sure I'm not the only one that has this problem so I am wondering. Is there a way to replace or retrofit a new dead pedal or foot rest. What I am talking about is the plastic piece that your left foot should rest on when driving. After 25 years the plastic has become destroyed and is totally gone. I would really like to know if I can replace this piece or if someone has come up with a creative solution to build one to put in?
Car in question is 85 300SD. Thank you!
