Though they might have the correct bolt pattern. As you can see by the picture, these wheels have a lot of back spacing. Which is normal on most late model cars, but may not work on your 69 Barracuda. In other words when you go to put then on, they may hit the leaf springs do to the large amount of back spacing. You would have to physically try them to know if they would work. As far as the age of tires, if you look on the sidewall, you will see DOT, look at the last 4 numbers after that and it will tell the manufacture date. Example, if it said 4113, that means the 41 week of 2013. 0615 would be 6th week of 2015. Stay away from tires over 5 years old.
