I removed the brake caliper and axel nut (why did I waste a good cotter pin?), and the bolts holding on the axle assembly so I could remove the two washers under the bolt heads, then reinstalled all of it (except for the tire and brakes) to start adding the U-0003 assembly which will hold the inner wheelpant mount.
Then I ran into a problem. I could not get any of the AN3-4 bolts to thread into the appropriate holes.
I confirmed with Van's that the hardware callout is correct, so I guess I'll find a tap to run through the bolt holes.
