You can super glue gel this in place once everything is done, as well as use the 2 tach screws that originally held it together. The entire assembly can be removed with the small factory screws just like stock. I put enough glue to hold it together but not so much that I couldn't take it apart.
I used a black sharpie to 'paint' over the Bosch lettering. I also painted the needle orange to match the factory gauges (this pic was before I painted it)
