I need to take both front and rear bumpers off. Can anyone give me help as of to what size bolts and how many are there?

 

Attached are a couple exploded view pictures of the bumpers. 3 large (M12?) bolts plus the little strap (M8?) per side for the front. It is a little tricky to remove without completely removing the side straps, but is possible.

The rear is just 3 bolts (M12?) per side, the inner bracket does not need to be removed.

Hope that helps.
