I bought these for my '05 with the factory spare carrier and they will not fit without some grinding, sanding, cussing and probably lots of beer. They're the only tow-rated rear hooks available and I paid approximately $180 for these (they list on RealWheels site for $163.15 plus shipping - they're the ones without the bolt covers). Will sell for $140 shipped anywhere in the good ol' US and maybe even Canada. They've never been mounted on my truck and include all neessary mounting hardware. Two bolts on each side and you're on your merry way...
