I am so sorry but we have no way to look up these items on this site. I would try eBay for used ones, otherwise you can't replace these kinds of toy parts with new ones the manufacturers just don't make them as parts that can be ordered
You can visit the website: http://www.littletikes.com/replacement-parent/icat/replacementparent?setpagenum=
All you need to do is enter the product number found on the bottom of the bed and it will pull up any replacement part you might need. If you would like to try an alternate route, there's always other sites such as eBay, Amazon, etc., however, the parts you purchase are not guaranteed to be the exact ones you are looking for and you may lose money. I hope this helps.
