it depends on what type of bike mounts they are. if they are the fork mount style, then you have to use the yakima racks. if they are the upright style (front tire attached), then you should be able to use yakima mightmount (part # 24h, $30 for 2 pairs) to hold them. for you ski mounts, you only need their mightymount (part # 2v, $21 for 2 pairs) to attach them.

for more information, check the yakima website

personally, i would just use your rack and buy new clips - if you're on a budget. if not, get either the railriders or their new control tower and mount it to the factory rails. i personally like the look on the rear of the runner instead of it being in front - especially if you have a sun roof.
