I buy my wheels from craft stores locally, but online is a great place espically if you need lots of them. Some of the big box hardware stores have them as well. Do you have a Menards? I know they have them, but don’t ask an employee they don’t always know they do.
I usually use a dowel for attaching the wheels. I find it easier to cut the dowel to the size I want then get the wheel to the end of the dowel, with out over tightening the wheels so they don’t spin.
