Hey Cecilia! Thanks for reaching out! I've got some good news and bad news for you! The bad news is that I don't have any stand alone adjustment plates for them (unless you're looking to replace the brakes, in which case I do, find them here). The good news is that I don't think you need an adjustment plate anyways as all of the ION bindings come with a built in adjustment track on the heel piece! It's adjusted via the Phillips screw at the bottom of the baseplate near the top sheet of the ski.
