I'm pretty sure they are the same as in our 2012. Dura Faucet

The parts in our bath faucet sure look a lot like the Delta parts, but I just ordered the parts from Dura and didn't worry about it. Price was decent and was delivered fairly quick. That was a couple years ago. I didn't bother with this, but according to their web site, the warranty is lifetime to the original owner, so you can probably get the parts delivered at no cost. Just check out the warranty link on their home page.
