I replaced mine recently. I found the aftermarket wiper, but it was more expensive than from the dealer when you added in shipping. It is a Trico and I found it at wipers123.com. You may be able to find it less, but I had no luck.
If you are getting it from the dealer, don't be tricked into getting the arm. You don't need it. The arm was about $40. You just need the blade or the refill. The blade was $12 and the refill was about $4. I got the blade just because I messed mine up trying to use a generic refill.
I don't use my wiper anyway. That back glass is too soft and road grime easily scratches it.
