Hacker help: Where to find Broder Clones?

Materials: Border Shelves

Description: I purchased some Broder Shelves and arms expecting to pick up the posts and feet at another store. After making the purchase I was told that this line was being discontinued.

So now I have the perfect shelves for my closet, but no way to mount them. Any idea where I can find posts that would be compatible with the Broder line?

Thanks
