Oil filter washer question CL77

[eyedragaknee]

Any idea of the size(thickness) of the washer that goes on the shaft between the cartridge and the outer housing?

I took the filter out to clean it and it is MIA. NO it didn't fall off in the case. I have taken these things apart before and was really careful and had drained the oil out prior to that.

Just bought this 67 CL77 and the PO or dealer probably lost it. I can probably find something or make one from shim stock if I knew the thickness.

Thanks
