Im taking our 68I back to original parchment/ivy gold from it current black. Im looking for some vinyl dye for some soft interior that is in good shape. The catalogs list two, light ivy gold and dark ivy gold, both listed as correct for 68. The carpet in catalog is obviously light ivy and the only option, but the heel pad looks quite a bit darker. Did Ford/Mercury use both in same year, if so, what should be what? Did they make a color changee after a particular date? If so when and which color was first/second? Any and all help is appreciated. Thanks.
