I decided to install my Gen III rear plate with a solid 4 point mount instead of the stock 2 point mount. The labels on the pictures should make them self explanatory. I also but some EPDM rubber weatherstrip on the back of the plate to keep it off the paint. Because of tools and material I had on hand, I added two #10-24 Riv-Nuts to pickup the lower two license plate mounting holes. The two stock upper mounts are M6x1.0 thread and I would have had to bought new tooling and Riv-nuts for my Riv-nutter to match them. There is about 2 inches clearance after you drill through the sheet metal, so with a small amount of care you won't run your drill into anything. The Riv-nut tool I used was a Harbor Freight Item#1210, 45 Piece Threaded Insert Nut Riveter Kit for $16.99. I got the HF one because it would have cost me more than that just to buy the right sized nut fixture and nuts for my high end Riv-nut tool. Riv-nuts (Threaded insert nut rivets) are similar to the blind rivets (Pop rivets) that you can buy in any hardware store and many car parts stores. Unfortunately, riv-nuts and the installation tool can be hard to find. The difference between Pop Rivets and Riv-nuts is that Riv-nuts have a threaded hole in them that can be used to screw conventional screws into. They are useful tool if you are ever want to securely attach a screw to sheet metal. Image 4 is a closeup of an installed Riv-nut and you can see the threads in the center of it.
