The brakes are the same. All you need is the adjusting hardware. Any bendix with 11" should work. Some of the hardware upgrade you need should be obvious. Some, not so obvious. For example, The adjuster with star wheel has finer thread on the self-adjusters. At one time, you could find all of this at your local parts store. If there are some "old" parts stores in your area, you may be in luck. Otherwise, it is off to the bone yard.
