Hello all. Well, my wife left me with the kids so I can't go out and measure the bolt and leave them unattended. I need to know the socket size of the bolt head. I know it's bigger than 22mm because that is the largest socket I have other than the BIG socket for the fuel tank screen. It's an '85 300d turbo. I've searched on here and on google and can't come up with an answer. She said she would get one while she was out so I need an answer sooner than later. Thanks for your help!
