If it is the factory rack and will otherwise fit, I might suggest cutting up an old inner tube for rubber padding, and stainless steel hose clamps come to mind as holddown hardware that is a bit more substantial than ziptiesShoot, just use washcloths instead of the pads and ziptie it down.
Shouldn't be too hard to stop by the hardware store and rig something up. (I wouldn't use zip ties though. Maybe duct tape. ) HAHAHA
If it is something you need, looks like a screaming bargain. I had an old $500 safari rack for a Land Cruiser in my garage for years and eventually let it go to a local kid for $75 or something because I *just* was never gonna use it again.
