How much does this rear bumper weigh? Removal...

[Gigem]

I am trying to remove the damaged rear bumper on my 72 GMC. The bumper and brackets are all one piece, so I can't take the bumper off the bracket unless I were to cut it and I don't the tools to do that.

I got the back bolt out on each side, but before I get the front two out and drop this thing on my head and kill myself I thought I'd try to see how much it is going to weigh.

Any tips on how I could support it to keep from killing myself with it? I am thinking I'll try to put a couple of jack stands under it, but I don't really know where the "balance point" will be....

And as you can see, it's going to land on my exhaust. Maybe that helps keep me from crushing my own head....
