I believe those two holes get sized for AN3 bolts anyway so i would do a quick check with Vans. As a side note, I have a few AN3 bolts in place of rivets due to mangled holes on difficult rivets. Not ideal but Neither Vans nor my tech counselor had any issues with their use.
Wings, empennage and fuselage completed
