I have to say, it's looking good with those 18" wheels.
Have you had a chance to put it through the paces and see how it handles?
FYI: 1977 is a "transitional year" meaning there are unique conditions combining technology of early cars, early mid-years and the later SC's. What this means is that when you want to post a question about the car, best to include the year in the thread title, just a helpful tip.
Transitional Year = Bastard Year
You might see that written sometimes.
Welcome to the club.
EDIT:
Is that still a true narrow body, or did the previous owner add SC or other rear wheel flares?
