leveling screws. Using the allen wrench and pliers, remove the screws
holding the back two clips on. Set the screws and nuts aside for later.
Step 5: Attach the Magnetic Base to the stock bed heater using the
included M2.5 Screws. The mounting holes in the Magnetic Base line
up with the small slots where the retaining clips that held the glass
plate used to be.
