Step 3: This can be nearly impossible to do without a few tricks. Even then it is best to get at least one helper. | |||

* Nuts should still thread onto the end of these modified bolts -- that is good for now. Obviously, you'll need to use unmodified bolts later for final assembly. I actually didn't install any nut (or washer) for most of the work in this section. | * Nuts should still thread onto the end of these modified bolts -- that is good for now.

* Note that the sentence in this section that refers to Detail C doesn't actually apply until you attach both elevators ("Not completely filling the gap between the elevator horn and the VA-146..."). That sentence is letting you know that it is important to fill the gap complete (I found it confusing). | * Note that the sentence in this section that refers to Detail C doesn't actually apply until you attach both elevators ("Not completely filling the gap between the elevator horn and the VA-146...").

Step 5: Now this is where you use Detail C from the previous page. Make sure to fill the gaps as much as possible and fully tighten. Make sure the elevators are perfectly even before drilling. You can use flat dental floss to help get the washers in place, and/or Washer Wrenches. It's tough to get two washers in one side without some dental floss. | Step 5: Now this is where you use Detail C from the previous page.
