are there any ski/snowboard carriers/racks that will fit the factory crossbars?

i have an '06 wrx wagon and the THULE 6 ski-carrier is too wide for the rear crossbar...it's about 1 inch too wide with the fatmouth clamp. :confused: so i called Thule customer support and they said the 6-ski carrier doesn't fit on the subaru factory crossbars. i don't want to get the shorter carrier because it only carries 2 snowboards.

i was wondering if anyone had any prior experience with this and can offer some input.

thank you.
