...The bolts go down from the mount .... the nuts are on the bottom ...early or late car?
Check out PET figure 119-00. I heard the advice that the nuts should be above the mount, that is, the bolt is inserted threads up. The reason they said this is that if you drag on, say, a speed bump where you could bend the threaded end of the bolt (if inserted threads down) you could "never" get the nut off ... if you drag the head on a speed bump, you scrape the head. 'Course the best advice is to never hit anything at all ...
EDIT:that's PET 119-00 in mepsteins post. The PET says 16 is a pan head bolt M 10 x 90 so you can measure yours ...
