When I tried to place the horizontal stab in place I couldn't get it to line up with the holes in the upper longerons.The reason was the #4 former was to far rearward.On the right side there was slight gap.
Sonex should put out a revision telling builders not to rivet the turtle deck skins to the #4former till the tail feathers are clecoed in place.Then you would be able to push the former against the spar .

Indeed ,I removed the rivets on the #4 former,which allowed me to line up the holes in the longerons, used the clamp to pull everything together and will now re-drill the holes in the former and re-rivet.
Moral of the story don't rivet your #4 former till you have your Tail Feathers clecoed in place.
