The Drake Muscle Cars Billet Oil Dipstick Handle is made out of durable, beautiful billet aluminum with a clear anodized finish and will surely stand out under the hood of your Mustang. Changing the dipstick handle is very easy. You simply remove the pin from your stock handle, place the factory dipstick into the replacement handle and stick the pin back in, connecting the handle to the dipstick. The O-ring you will need is also included to make proper installation a breeze.
