What is the name of the blue Soc car in The Outsiders?

In the book The Outsiders the Greasers are harrassed by the rival group called the Socs.  The Greasers wear their hair long and slicked back with grease.  The Socs are the more affluent kids in society.  They own cars, have money, and go off to college.  The Greasers survive in lower income families.

One of the Socs named Bob owns a blue Mustang.  Whenever, the Greasers see the Mustang they know there is going to be trouble.  None of the boys like to be caught alone when they see the car.  There are usually several of the Socs in it cruising to create problems.

He had been hunting our football to practice a few kicks when a blue Mustang had pulled up beside the lot. (33)
