What do you recommend for a backcountry repair kit?

There are no parts that are likely to break and leave you stranded. A tail throw or heel tube are the two most popular items to carry for the 75mm bindings. And a Slic pin if you like to swap them in the field. Some Outlaw skiers like to carry a spare Claw. We also sell a universal backcountry repair kit that doesn't have binding parts, but can fix just about anything.
