As you know, Lebaron Bonney ceased operations a while back. So did Cartouche, another interior kit supplier. If I get the lineage right, Mac's bought out Cartouche then Mac's was bought out by Ecklers and they got bought out by yet another firm. The last sale killed the Mac's-Cartouche business. Maybe Cartouche bought out the patterns from Lebaron Bonney, but I don't know for sure. Regardless, I don't think there is anyone left making Ford interior's on a commercial basis and who knows what happened to the patterns and information.
I suggest you call ThirdGen in McMinnville, TN and speak with Michael. If anyone knows where you might get an interior kit for your car, he's the guy.
