Stockton Wheel in CA carries a lot of wheels, and they can make about anything. I've not used them personally, but have heard several positive referrals.
Also, Midwest Wheel Cover in MN carries a lot of wheels. Most are custom, but I was able to locate some used plain steel wheels for my truck there.
Good luck. Those stock steel Wheels seem to disappear.
