Now that said, even though I don't agree with it, you can sometimes put a whole different Front Clip (the whole Front End of the car as a unit) from one year to another. For example you can put a '65 Front Clip on a '66. Also you can probably put a '69 Front Clip on a '70. But in '68, it is '68 only. A '67 Front Clip will not work because of the Windshield Wipers. In '67, they are exposed and in '68, they are hidden. Unless you wanted to do some retro-fitting, which I really don't recommend, lol.
