Installed the coil mount tonight with the aid of a threaded insert riveter. If you’ve ever used a regular rivet gun, you can use a threaded insert riveter. It’s a great tool for adding mounting points to all types of sheet metal. You can pick one up fairly cheap at your local hardware or automotive store. I got mine for $19.99 and it included 45 inserts of various sizes and the tooling for those threaded rivets. I put together a quick little video (sorry for the SD quality, my GoPro wasn’t charged) to demonstrate how easy it is. Enjoy!
