Yup, most factory wipers can be rebladed too, which makes it even easier (and cheaper than 3rd party). If you don't
live near a dealer (like I do), then it becomes harder to get them. I've had a lot of luck buying wipers off enthusiast parts suppliers (say you own a mustang, go to the famous mustang online shop.....they will have easy to use wipers).
If you have a car that doesn't have an enthusiast or cult following, you might have to order from the dealer online, which can be a pain.
