Thanks guys,
I see the that Thule has a 450R Crossroad foot with a metal/rubber strap that may work then the cross bars attach to those, then the ACTUAL ski rack gets mounted to the crossbars. Jeez. Even used parts on local craigslist would total out at around $400.
Apparently, Thule's official solution is to use "super tall gutter mounts" with the square cross bars to get above the tubes.
Amazingly, the Genuine Land Rover Parts division back in the U.K. has a ski rack for 90 pounds Sterling that is supposed to fit on all Land Rovers with a gutter.
For the price, it cannot be beat.
I'll sniff around for X-terra racks. They did seem to copy a lot of the Discovery styling q's
