Red: More Shiny Bits

Picked up a few little things at the hardware store.  8mm acorn nuts with 10mm washers for the cushions.  Small cotter pins for the pillions and rear brake stay bolts.

Had hoped to add the upper rubber cushions under the holders, but realized that if I did that, the bolt doesn't extend far enough to then put on the lower cushions, washer and nut.

The holders with the alignment pins are of the right length, but I'd need to grind down the pin.

But then the question remains, why don't the holders without the pins fit?  They must have used a different setup of cushion and washer, given that the fork bridge wouldn't have changed thickness (I assume).
