Been searching google images & finding a limited supply of picts, put it appears at least the the pan should, or possibly "might" be sort of flat in that area, but maybe not the dents that are there? I also saw a couple picts that looked rounded, but I don't think there were 68 pans. drain was on the side. I realize this area is fairly hidden from sight by the frame, but easy to correct if its wrong now... Not so much later on
