Looks like them. You can order straight from their website here: http://smoothdrag.com/
It's a little awkward and old school. But you can call them to place your order and they send you an invoice to pay, or you can email them, and they will respond with an invoice. If you are unsure of what you need you give them the make and model of your reel and they will let you know if they have what you need. Their customer service is good. They do keep pretty tight business hours, so if you call a little late it might be best to email.
Might be a good idea to open the reel up first, you never know if you will find you might need to replace a metal washer or something as well. Just before you order, that way you are getting everything you need first shot.
