The boots (part #16, or 51571-11010) are still available from Suzuki, or for a better price from Cruzinimage on fleaBay. The nylon spacer (part #18) is really tough to locate - try a PM to member B100P2 on this board as we had a lead on a fellow willing to make us some, but I'm not sure of the current status.
I'm sure other's will chime in on the other parts.

If at first you don't succeed, just get a bigger hammer !
