Today, I started locating the door strut brackets on the cabin top and the door. I have the PlaneAround strut brackets, which are machined with the McMaster seal in mind. Even so, these things are a pain to get match drilled in place. What I ended up finding worked best was to match drill the outer hole first, and screw it in place. Then I drilled thru the bracket with a drill bit wrapped in tape to protect the threaded bracket. Then I removed the bracket and final drilled the holes. I also made a template to help locate the brackets on the inside of the door, and used it to match drill them in place.
