I ordered mine from
www.automotiveinteriors.com
They're actually selling ACC Mat (
www.accmats.com), but it's cheaper. Cost me $135 + 13 for shipping, and got here in about 4 days.
Actually, I just checked their product listing, and they didn't list anything for 5th, 6th, or 7th generation preludes. It's possible, however, that they may have products for your car, and just haven't updated their web-site yet. So give them a call.
