Try Falcon Enterprises, Dearborn Classics or maybe Ken's Falcon. Mine are from Dearborn and were great. Original type material, perfect fit and look. I've had it in the car for about 11 or 12 years now and it's held up great. My fronts are buckets and I also bought their complete interior kit which came with door and rear seat panels, kick panels and headliner.
Good stuff.
