Anyone on fabo know a lot about F body cars?

So I have what I thought is a 78 volare wagon but apparently the vin says it's an aspen. (I do not know the vin codes for F bodies) (NL45D8)

The car was missing the hood and grille when I bought it.

So a friend knew I am looking for F body parts and he texted me a pic of a complete 4 door donor car...... but it's a 1980 dodge aspen. It's reasonably priced and available.

My question(s) are will the grille and hood fit a 78?
I know by visual appearance the 80 grille looks a lot more square and different than the 78 stuff.

Would the 80 be a useful parts car for the 78?
