I ordered a set from Ironwooddesigns for my Saiga .308. It hasn't arrived yet, but I e-mailed matt at ironwooddesigns.com and told him what I wanted, he recomended what he thought would be best. He was able to make the sling swivel cut on the right side for me, since I am left handed, which was a nice touch.
He was recomended to me by "Dinzag" from the Saiga forum.
The sets are unfinished, but the webpage has a tutorial on finishing them.
