Here are mine, that I had a upholstery shop in Memphis order me, I have no idea of the company that made them though, they are made for the xB, and came with new clips and all. I think with the embroidering it was about $100 for all 4.
here is the shop that I got mine from, you could call them and see if they will tell you the company that they order from, or you could prob just order from them.

and here is a pic of mine in DOA. They are thick and seem to be well made, I don't keep the fronts in all the time though, I only put them in for shows.
