Looking for older model Little Giant automatic egg turner.

I am building an incubator using a meat shipping box. The new style of egg turner from Little Giant measures 15" X 15" and cannot be shortened down because it replaced basket trays with solid trays with holes. My box mesures 13" X 18". I am looking for an egg turner that I can adapt.

 

I took your advice. I checked out the newer model of egg turner from Little Giant and noted that it was an easy fix to remove the one rack on the end and then trim down the frame. The turner fits like a glove. Thanks
