Mystery Shock Washers..? Options

[Olympic 914]

Putting my rear shocks back together and I have a couple shock blow-ups but they are not clear to me which washer goes where.

Heres what I have.. at least this was what I had in the "rear shock" baggie.

(not pictured is the washer that goes on above the top rubber bushing )



does it go like this.. with the big washer that looks like a fender washer?



or with the smaller one that is the same size as the bottom of the threaded bushing. #5 in diagram.

the smaller washer seems to have been specially machined for something like it may have gone under the lower spring retainer on the original shocks, but I am putting on KYB shocks and there is a shoulder that the top spring retainer rests against.
the recess in the washer does not fit over this shoulder.
