Key/Lock replacement?

Hey guys I have a 1968 Barracuda that has not ran for 28 years, and last week we finally got it started. However over the years all of the keys have been lost and I was wondering if there are any differences between the lock and key assemblies from 1968 to 1969. I thought they were the same from 67-69, but I found the following set on the Year one website and it’s listed as being for a 69 model.

Just want to make sure I don’t get something I won’t be able to use. Also open to any other suggestions as far as vendors ect, thanks.
