Basically, the only things I left alone was the Pontiac emblem and didn't chop it and did not convert it to a two door model.
I shortened the antenna, changed the rear spoiler and added highlights to the windows too. Every time I changed one thing I had to change something else. I wanted it to look uniformly different. I did not like the the bottom half of the front end and everything else followed. That is what I start with...the front end...the "face" of the car.
