I have them. Unfortunately, my car's in the shop getting some suspension parts installed but I followed the Z1 installation guide for their hood struts since it's exactly the same.

If I recall correctly, I put the washer on the nut side, but according to the instructions above, orientation doesn't matter.
The Q-tip is used to put the grease inside the cups prior to snapping them into place so they don't make noises.
Hope this helps some.
