When you look at that link, be sure and be logged in so you can see some pictures. I posted a solution to keep the brackets from trying to "skew" to the outside by drilling holes in the brackets and running an all-thread bolt about 42 inches long between them.

While the original picture at that thread of the full door and all of the all-thread was blurry, here is a clearer picture of my solution to bracing.

It won't stop the screws from coming out, but it does help to stabilize the brackets and the closure cylinders. My solution with some of the other ideas could be valuable to you.
