Yep, I did. The one I took out of my engine was the center one, as was the part I ordered, INA-5320605100. The bolt just could not fit through. Seems like the inner diameter was just a bit smaller than the original.

I uploaded a comparison here:

The left pulley being the original, along with the bolt suggested (07119906591). The one on the right is INA-5320605100, which I could not thread the bolt through.

I ended up getting a Duralast idler pulley (part 231161) that was suggested in another thread, and the bolt threaded through fine. Been driving it for a week now with no problems so far.
