Just a note:
Those 4 fasteners that attach the front suspension cross-member to the body should be grade 10.9 bolts. Most fasteners on the vehicle are grade 8.8.
The two short bolts that are holding the steering rack cover to the cross-member can be 8.8. Those are not structural attachments.
PET is usually your friend for these sorts of fastener questions.
Item #2 M12 x 1.5 x 80 Grade 10.9. The longer front fasteners.
Click to view attachmentItem #6 are the 2 shorter rear fasteners that secure the cross-member to the body are M10 x 20. In this case M10 without a thread pitch means standard coarse thread. So these are M10 x 1.5 x 20 Grade 10.9
Dlee6204 and Van B got you your answer on the two non-structrual M8's that hold the cover to the cross-member. These are Item #9 M8 x 8. Again here M8 without a thread pitch is reference to standard coarse thread pitch for a M8 which is 1.25. So M8 x 1.25 x 8 Grade 8.8. 8mm is a pretty stubby bolt. You may not find it in stock with Bellmetric. If you don't, that is what the hacksaw and file are for.
