A bit late to reply, but I ordered carpet for my 64 on 72 IRS pan Ghia from Newton Commercial,and when they heard what I was doing, they sent me several patterns to try out no charge.The floors are out of a 64 pan so the only different piece is the tunnel, but if I had used the 72 floors,I imagine seat differences would enter the equation.Expensive,but really nice stuff.If I ever put another car together,I would do it again.
