Overkill Off Road was a sponsor for the 2008 TTORA TakeOver, and they donated a couple of their Tacoma rear bumpers.
They were pretty simple, and pretty stout, and pretty inexpensive, I think.
If you google Overkill Off Road, it's the wrong one.

I might add, Anthony has different brackets for trucks without body lifts as well as trucks WITH body lifts, make sure and specify your needs when ordering!
