I have several 17x5 aluminum spares that were optional on the 00-06 Lincoln LS. These have a 5x108 bolt pattern, and by themselves, the wheels weigh 13.5 pounds (not sure on the weight with tire, but I can weigh one, should you want that info).
These will clear 13" Cobra brake conversions on the MN12 platform (and probably the 89-95 SHO, but I'm not 100% positive, as I don't have one of those). May also work on newer stuff like the Focus ST. They're also handy as drag strip skinnies, though of course I wouldn't recommend using the tires themselves for that purpose.
As I said, I have several of these. All are true, but some of the wheels and tires are in better shape than others. I've included one pic as an example, but can supply multiple pictures of each wheel on request.
Price is $50 each. I'd prefer local pickup (near Chattanooga, TN), but I'm willing to ship if you're willing to pay for it.
