WTB Anatol or M&R slide on shirt boards 18x22 or 18x28

United States

I am looking for Anatol aluminum shirt boards with the slide on type brackets. I understand that M&R slide on brackets will work as well. Looking for minimum of 18" wide x 22" long or could be as wide as 20" and 22" long. 28" long is ok too.
