HELP!!!!!! Replacing clamp on an XT cap driver HELP!!!!!

[Judy]

Because I work when I am half asleep, I changed from embroidering a flat to embroidering a cap. I set the cap driver on. I hit trace. I found out I forgot to upload the cap design, and traced the flat design, which was too big for the cap driver and resulted in a broken clamp on the right side. I ordered the clamps from Melco and have them in possession. Any tips or tricks I should know?

AND ESPECIALLY....WHAT DO I USE TO UNSCREW THE NUTS HOLDING IT IN? THEY LOOK ROUND ON THE INSIDE!

The answer is it takes a hex wrench from the tool set. Undo the screws, take off old clamp, pop on new clamp, tighten. Adjust the nuts/bolt on the end with a 9mm box-end wrench.
