Problem is, the Buttondown was discontinued a while back. It's replacement (Powderhound) will take the mounting bolts vertically, so it would work with your universal mounts. They used to sell specific Mighty Mounts that would fit around your stock rack bar and allow you to mount the Buttondown (I had one years ago). So you can get a new(er) ski mount (Powderhound); try to find the right specific Mighty Mount on eBay or somewhere; get new bars; or do what people here do, buy a ski box to protect your boards from theft, road grime and moisture. However, if you hide your boards in a ski box no one knows you ski do the cool factor is lost. Good luck. Those Buttondowns musta seemed like a good deal at the time ....
