Theres a lot of excess metal at the bottom and behind the license plate fixture that can be trimmed off to make the bumper itself lighter.

As for mounts I used aluminum camper awning posts, pretty strong. Ran them straight off the frame side rails where the factory brackets mount. Ran that straight forward until it meets the bumper where it needs to be. From there you can either weld or bolt on u channel bracket to tie into the U channel aluminum post.

Can send you pics if you want from cell.
