New Zealand Datsun Club

Desperately need the stopper assemblies that fit on the rear brake back plates that hold the handbrake lever assemblies inside the drums on 810s. They look like pins sticking out on the inner side at the bottom of the back plates. May be other Datsuns have them ? Unfortunately my inexperience with these brakes has come at a cost and have been told the stoppers are no longer available new.
Please let me know if you can help ? Cheers.

Picture???????

Not very good but the best I have. Plastic grommet pushes into the bottom of back plate. Will pay of course if someone has any they want to sell. Hope it isn't karma for taking a Sunny from Christchurch !
