Note: Remove the factory thread adapter and measure for the proper thread size. (If the thread size is smaller than 9.6 mm in diameter you will need the version 1.5 adapter)
You have to remove the factory threads first. The factory thread has two flat sides where they can use a wrench to turn it counterclockwise to remove. Then add on the DonnyFL adapter.
