Good luck. You might be able to find a rack that's close enough but the rack supports, 257054 and 257055, are going to be hell to find. You'll have to make them yourself. According to the picture on Repairclinic, the rack looks like it's about 23" x 17". I just checked the racks in my Whirlpool range and they're 24" x 16", probably just a little too wide.
