I would buy one, the flimsy aftermarket bumpers are $150 last time I
checked.  Make sure the plastic end covers fit though.

I have actually been able to straighten out the original a couple of
times, but the last encounter with a 55 gallon drum filled with concrete
and anchored to the ground not only finished off the bumper but the rear
valence panel as well!  Fortunately, it was lower than the hatch, or I
might be looking for a new Westy.  Only a bumper made of quarter inch
thick steel channel would have prevented the $800 worth of damage (which
I pulled out by chaining to a tree and rolling down hill!), and I have
contemplated doing that too when I repair it properly.
