ride bindings are notorious for problems with the straps and hardware. I would honestly just recommend getting yourself into a new pair of bindings. Although, if you are dead set on getting a new ratchet, it isn't hard to do on ride bindings because instead of doing what a lot of companies do and rivet their ratchets on, ride uses a screw that you can just take off. From there, you just need to find a rachet that will accomodate your ladder strap and fit correctly on your toe strap.
Hope this helps.
