2.7L idler bearings

I'm trying to order both idler bearings but the part descriptions are confusing and contradictory. Are both bearings the same? If so, why are they listed separately and with different prices? What should I buy?

 

Do you want bearings, or pulleys? The pulleys are all different, no idea on the bearings. If you buy bearings on Ebay they will most likely be garbage and won't last long.

 

I misspoke. I want the pulleys. I,m going to call a Toyota store.

 

As an FYI for anyone in the future, one of the pulleys is hard to find in the part diagrams and is on the drawing for the timing chain cover, or similar. Not easy to find.
