Seems like a never-ending series of steps, but at least this one is in the bag! This weekend I used a slide hammer to remove the studs, and removed the gear from the plane. This technique worked great, by the way - if your landing gear studs are "stuck", try a slide hammer. They're inexpensive, and you can attach them to a nut and washer on the end of the stud to pull it out. It took a while - the thing only moved a millimeter or two with each blow - but it was definitely the right tool for the job.
Adding the washers to the outside faces of the attach tabs was a pretty simple task. When it came time to fill in under the support MKMGA tubes, I routed the brake line through that section to give it some support. Other than that, not very exciting. Sometimes that's a good thing.
