Nadvys--That bolt is a real bugger. I took a metric (Taiwan) metric wrench and flattened the box end and bent the wrench (spanner) to a right angle. I then glued the nut into the box with the washer and the operation went slick after that. The time was spent in thinking about it and modifying the wrench. PaulJ said he was able to reach up somehow from under the car. Good Luck
