Missing Parts in Rear Drum Brakes

[PeterPortugal]

Hi all,

I am missing some of the parts used in the bolt which retains the service brake shoes at the bottom. The car is a 1963 with the rear drum brakes.
I can get most of the missing pieces but part number A120-423-01-56 which I believe is a brass washer / ring is no longer available. When it was available it cost 10 bucks so I am guessing there was something special about it.

Can anybody suggest alternatives to use?

Regards

Peter

Wow....just after posting that I managed to find the sucker. The "special" part about is the hole is rectangular.
