'67 Barracuda Question

Can anybody tell me the difference between rear valence for the 1967 and 68,69. Barracuda. It looks like AMD makes reproduction, but they only list it for 68 & 69. The one on my '67 is in pretty bad shape and I would like to replace it. If its only minor tweaking I would buy it, but if it's totally different then I guess I would have too fix what I have. Thanks
