The Mustangs come in two flavors......plain and studded. Here's a link to the Mustang site.....
http://www.mustangseats.com/Category/Saddlebags-LuggageThe studded version's part number is 13300.
When I bought mine, I bought them here (back when I bought them, the price was a few dollars less than they are now).

They are hard bags......and the rails are OEM. The bags come from Mustang covered in their fax leather material. It's not a cheap covering......they're very nice.
For both of you guys......
The bags are NOT a direct fit.....especially using the OEM bag rails. I had to massage them to make everything work.
Alot of folks use the Easy Brackets to mount them. Here's a couple responses to someone that asked about mounting them with the Easy Brackets (lots of pics).....
