I've been going over my new (to me) '86 300E fixing several little things. One of them is replacing the headlight wiper blades and re-aligning the wiper arm.

Can't figure out for the life of me how to get the old blades out without the risk of breaking something. Can anyone shed some light on this procedure for me? Also, how can I remove the wiper
blade arm to re-align the arm properly.

Thanks,

Gary
