Thule-Yakima ski rack mount

I needed mounts to fit my Subaru-Yakima ("powderhound" style) ski racks onto my older Thule load bars (LB50 rectangular bars). Zip ties worked OK but didn't hold up well when temps got below -20F and they couldn't make it through the car wash. These do just the trick. Fit is snug & secure on my standard-issue Thule rack and they slot into the ski rack well.

Each mount requires:
- Load bars: one 0.25"/6.5mm nut and matching threaded hex head bolt (1.25") for the load bars.
- Ski rack: one 0.25"/6.5mm square neck carriage bolt and matching wing nut. Yakima uses 2.25" bolts..

I get a bit of extra wind whistle at highway speeds which may be eliminated by increasing the gap between the rack and top of the mount, but that'll be for the next version...
