The fuel door lock on my '82 300D is broken, so I stopped by the local parts store to purchase a locking cap. Much to my surprise they had nothing listed for the car! Does anyone know if there's a locking cap available? I realize the right thing to do is to fix the (missing) fuel door lock, but I'd like to have the security of the locking cap anyway, I think.
By the way, the conversion has over 100K on it now, still running strong.
