Rock Auto idler pulley w/ no bolt.

I ordered an idler pulley from Rock Auto and the foot note reads "no bolt."

Should I install the pulley with a new bolt and washer, or is the old hardware fine?

The old hardware will be fine. I've always reused them without any issues.

Also, most new idler pulleys will not fit the old flat washer. Don't worry about it; most are designed to install without a washer if the old one doesn't fit.

The washer I have is dish shaped.
