WD-1008-L / WD-1008-R step weldments have 16 holes each. The corresponding F-1021-L / F-1021-R outboard baggage ribs are missing four of these holes, with no instructions on the page to match drill. Vans support confirmed (12/15/2022 - Gary Keyser support engineer) that it is acceptable to match drill through the WD-1008 into the F-1021 and rivet. The plans corroborate this as they call out 32x AN470AD4-4 rivets. | WD-1008-L / WD-1008-R step weldments have 16 holes each.

Step 9 refers to "keeper rivets" which I thought meant temporary rivets, but that's not correct. You put the AN426AD3-4 rivets into the two places per side like any normal rivet. You do NOT put anything in the other five rivet holes on each side as part of this flange. Later (Section 29), the skin will rivet into those other five holes, and the keeper rivets will remain where they are, hidden underneath the skin. The keeper rivets keep everything together until the skin can be properly riveted later. | |||
