I am hoping that someone can come to the rescue! My 1975 Renault 12 has decided that it doesn't want to carry any passengers in the front seat, and has dropped the little pin in the locking mechanism down and effectively jammed the front door. I have tried to get at it from every which way, taken door panels off etc., but no go. Does anyone have any suggestions - PLEASE.... Yours in hopefulness...... John.
