FYI, I did line my firebox with firebricks I got from Northern Tool. They are regular 4-1/2"x9" but only 1-1/4 thick used for wood stoves. Box of 6 is about $13. They are easy to cut to size & shape with a diamond wheel on my small Makita grinder - they work great.

The firebox wheels come off when it is in use and it has steel feet it will sit down on.
