Help please! 3x 10mm bolt size

[bellis_GTR]

Hi guys. I need help quick. I seem to have lost the 3 10mm bolts that go on the head. One in the front and 2 in the rear.

I know they are M6x1.00 but what are the lengths of them. If I remember the rears were the same length and the front was a bit smaller.

Please let me know!
