"Special washers", do they come by two?

I'm considering buying this updgrade to reduce torsion in my warp: http://www.ercmarket.com/product.php...cat=378&page=3

but the picture only shows one piece. Does anyone know if the package includes two or just one piece? If it's just one, I find it quite expensive for just a small piece of carbon.
It's even more ridiculous if someone has to buy this: http://www.ercmarket.com/special-was...-cb-block.html

Unfortunately it's for a single piece. I have both new and old and while the new one helps make aligning the pulley block and motor easier, it's no magic bullet if you think it's going to add much rigidity to reduce flex. Furthermore, once you have everything aligned be it old or new, you don't need to keep messing with it which diminishes the purpose of the new ones. Sure, nice to have for the initial setup, but not absolutely necessary.

But buy it if it makes you happy, lots of things in this hobby don't make financial sense anyway.

Alright, thanks.
