That link is for a 94 and up mustang. I asked this same question several months ago and it seems like most people just make their own. I luckily have a auto upholstrey shop a couple blocks from my house and I had them order a roll of carpet that matches my interior perfectly and I just went to the hardware store and bought some plywood and glue and measured the back and cut the plywood so it would fit perfectly and then glued the carpet down. I think it looks great because the carpet is the same color. If I had a digital camera I would show you a pic. But there are a couple guys who did this same thing and have pics
