68 front clip on a 69?

[69-Chevy-350]

I was looking at the new issue of Classic Trucks and saw that phat ass 72 Chevy with a 68 clip. I think by far the best front end is the 68 front. how hard is it to put a 68 nose on a 69? I am hoping it is a matter of just changing the grille.
Second I wanted to pass along to everyone that I tried the roll on herculiner and found it to be a great product. i did two coats in my long bed and still had enough to use as an undercoating for under the cab.
