Looks just like the ones I just removed from my '67, even has the backwards wound 'black' anchor spring, (forwards wound anchor springs are light blue).
I just bought a new Bendix set to mix and match with my originals. They have some parts plated correctly, other parts are not. For example, the round discs are originally di-chromate as well as the auto adjuster arm. The replacements are both zinc plated. I'll likely send out these original adjuster arms and the replacement discs whenever I get a batch together of similar needs. If that day doesn't arrive, they are going in as zinc (easy enough to fix later if I choose).
