It's been discussed at length here, but the posts are buried now and I can't find them either, so here are the best images I have of it. The part of the mod you can't see is that there are shock-seal type o-rings under the inverted purple cone washers bolted to the steering posts, and the holes that are enlarged are done so in the back and the front of the upper deck. This helps the upper deck "flex" and settle back into place without setting into a "tweaked" position.

Hope that helps!
