Get in touch w/ CKS in Nathrop.
They will get you squared away with whatever you need.
I, however, would be very surprised if much will be running on the Ark at that time. You should probably consider doing the lower blue just north of Silverthorne. It's great read and run III and really beautiful. CKS also has a shop right near by and should be able to get you whatever you need... well to a point... :0
