This area was not as easy to rivet as the rear HS. I had to drill out my first rivet on the project. I did not enlarge the hole. In fact I drilled out three all together and thats when it hit me. The -7 rivet was too long, the -6 was too short, why not pull out the rivet cutter that I bought and cut the -7 down to a -6.5. Worked like a charm.
