Welcome from Alabama
If you buy this kit don't use the bottom piece. Look at the original and you'll see it's 180 degrees off. The wipers will slam down when on and park in the middle of your windshield. Use your original bottom piece which is probably still good and the top piece from this kit and it will work on your 300.Maybe you've already seen these on eBay?
