I'm going to be doing the same thing to my tsunami

You will also need #8028(Bumper spring shaft) and #8032(springs) and screws.It also looks like you use shock mounts that attach this stuff to the shock plates

This will give you a good picture of how to put it together

Bring it up in Acrobat reader- go to the last page and magnify it-front and rear bumpers attach the same way and IMO the rear view shows a little better detail
