I only worked a short period in the hangar because I didn't feel well but I at least fit the right side of the stabilator skin. At first it didn't seem to fit well but I should've just trusted Van's expertise because as I clecoed, it fit fine.
I'm still going to ream the holes out to a true #30. A VAF emailer said the reason the rivets don't fit well is the punch Van's uses has gotten slightly warn over the years, so the hole are slightly undersized.
