1984 300d, doing motor mounts and started to strip the 8mm allen head bolt- stopped as I know I will need to replace whether I can get it out in one piece or not, but need to know what specs are on that bolt so I can have one waiting to put back in- or if someone has extra bolt let me know and I will pay you to put it in the mail for me! Also twisted nut off bottom of engine mount shock, anybody have an extra shock?

Thanks,

Dan- Niles MI
