I snapped some pics of the two pullies. The smooth ribbed one is the one I had issues with. This one was sent to me last November and it sat until spring.

The new one is a bit different. I see it was mentioned that C3 went back to the old style because they grip better? It looks like the "new" one that just showed up is "old" style?

Does it look like any of yours?
The new one that just showed up on the left, the one I got in Novemeber on the right. Overall the new one looks like it was put together better. I will probably get it installed tomorrow after work.
