i've seen this car before. Plymouth never installed a vinyl top like pictured on this car on ANY 67, 68 or 69 Barracuda. the above car also appears to be a 68 as it has a 68 grill and 68 tail lights. the below 69 Barracuda has the correct "factory installed" vinyl top - it was called a "slick back."
