Floorboard - Shift Lever Plate Clips

[Russ]

I'm making new floorboards and trying to make them to the original specs. The plate clips which rotate to hold on the shift lever plate came with rivets and washers. I believe I read somewhere on FB that the rivet head goes on the bottom of the floorboard. My question is: does the washer go between the wood and the plate clip, with the upset end directly over the plate clips (to leave a gap for the shift lever plate) or does the washer go between the plate clip and the upset end of the rivet, with the plate clip directly against the floorboard?
