I don't know about everyone else on here but the plastic of the housings on mine was very brittle, the original screws took most of the threads when they came out, so I used a hand drill, opened up the holes. Then I used a tap, found the matching screws, and used jb weld in the holes then when it dried I could run the screws in and out and tighten them unlike when I had just tapped the plastic itself. A few of my screw hole bosses broke, and I had to jb weld them back together, but it turned out well.
