Do it on the warmest day of the week, take your time when attaching to the header. That's the most critical part. Be prepared to go to the hardware store and purchase new screws if you existing ones end up rusty. I purchased new stainless screws and added washers to give a little more strength at the attachment points.
When my time comes, mix my ashes with gunpowder encased in brass, point me towards murderer's and pedophile's and let me fly.
