tube bumper on a 89 4runner
 

I want to build a simple rear bumper for my 89t4r out of some 3 inch pipe laying in my yard,just a single piece across the back with a hitch welded to it,my only problem is although I have done some welding in the past my "Fab" skills are kinda minor, anyone have a setup like this on their rig?How did you mount it? I want to mount it to the frame so if anyone has any pic of the brackets they made to mount the bumper to the frame it would save me some grief trying to design my own,thanks.
