tokico illumina rear shocks - top washer doesn't fit on shock tower

[paradigm]

I installed Tokico Illumina shocks on the rear of my 2000 GT, and the washers that came with are too wide and do not fit ontop of the shock towers in the trunk.

I would normally just replace it with a smaller washer, however these are special angled washers that are more of a hat-shape. Anyone know where to get smaller replacements from to fit the car?

Thanks
