Pleeeease don't fit a wagon rear bar! They look awful, plus you can't drop the tailgate anymore.

If you must find one, HJ to HZ Belmont (and possibly lower spec Kingsood) wagon rear bars are not all that common anymore. You might have to fit a HQ one, and these do look better than the HJ to HZ examples.

Give Greg (ozbox) a call, he'll freight the stuff to you quite cheaply.
