Man, where were you last week when I tried to follow another tutorial and had an epic fail , which led me to bag the idea and just purchase one. This is an awesome tutorial and I can see now where my errors were. All's not lost though, as I need to replace a neck seal for my son, and will be following this tutorial for sure. This will be a huge help to your fellow troopers down the line. Well done Gerald and thanks for taking the time to not only post your work, but for all of the detailed photos and instructions that make this tutorial an excellent reference.
