I put in new bushings and used the same coin-edge bolts that Chris did. I got them from McMaster and they rusted immediately. I didn't have my powder coat job done as glossy as Chris, mine is much more matte.
The guy had an awful time removing the plastic, the job got a B, and if mine wasn't rusting out, i probably wouldn't do it. That said, the spare tire holder came out much better than the 3rd brake light. That still looks rough.
