Hey Mike, I hate to do this but I'm going to as I purchased the same rack for $8.00 at midland hardware. Here is the post that was in the #3 section.

And if you are close to a midland hardware store you can order them and then pick them up at the store which will save you shipping.
Those racks are a pain to clean though. I prefer to just use the basic racks that come with the smoker, then put Q-Matz on top. Non-stick, clean up super easily or go in the dishwasher.
