Ol' Chevy at School

I have a hard time telling the differences on these trucks, its a 48 to 53. I saw this tastefully done truck in the parking lot at school today when i went on campus to pick something up. Usually when i see a nice old truck at school they usually have a crappy unprofessional paintjob with huge rims..this one was smooth as glass, had some nice torque thrust wheel (Ive always loved those wheels!)
