Looking for a replacement swivel base for my wooden rocker?

I am looking for a replacement swivel base for my wooden rocker. The piece of plastic that covered the bearings had came loose and some of the barrings have fallen out. Which was not the wooden rocker to spin in a 360 radius. I have removed the base and am now looking for replacement. Is there a place that I can buy a Swivel Base replacement?
I do not have a model # only number that I can see is on the bottom where the back and seat are bolted together it is 8079 and a sticker Made in China All I can tell you is it resembles the rockers that every large well known chain store carrie, that have a matching ottoman. It was bought for our baby shower 4 years ago.
