I got mine from John Kennedy (www.kennedydiesel.com - 715-255-9433) in Loyal Wisconsin. I think he advertises on this site, he is excellent to deal with.
The price is pretty high on these covers, but they are really well built. I don't regret buying one !! I had the side rails on my ReTrax sprayed with Line-X when I had my truck sprayed, which is also done over the rails so it matches well.
