Mounting Kit Recommendation for Fitting Thule Pull Top Carrier to Aero Bars

Hi, I recently installed aerobars on my Subaru Crosstrek. I have an older set up thule ski racks - they are pull top - I think they are the 726 or 725. Regardless, they have the square bar clamps on them and a screw on the inside of the rack with a plastic head for turning into the nut on the clamp. I am wondering how to convert these racks to fit either into the aerobar slots or connect around the aerobars. Help! Thank you.
