Good story, Dave.
Would you or any other team (present or former) have a list of what you bought as spares, as well as any major items you re-worked for an event such as this?
I would guess spares of the major stuff (rudder casting, spin pole, boom, rudder blade, daggarboard) is easy - although expensive.
Some of the smaller stuff is what usually cripples your performance (rudder gudgeon, spin block, downhaul cleat, rudder arm)...
