I am having trouble understanding the attachment of the center section assembly to the center section aft bulkhead. When you cleco the two pieces to the bottom skin, they will of course rock back and forth. A couple of 1/4 inch bolts initially set the position, but then it says to release the clamps and let it sort of self align! It "self aligns alright, to many different positions depending on how you hold your mouth! Of course after this casual instruction, you are to match drill 72 holes in what I suspect is a pricey center section assembly, and I would rather get it right the first time. Surely it must be more precise than that, right?
