DirtyOlds

Hello everyone! Well what I want to know is the dimensions for the radiator because I want to put in a new aluminum on with a fan. Honestly don't have any problems with the old one but would like to step it up because I plan on taking a few farther trips this year. So with after the dimensions if there also any opinions what to run in it that would be great!!! I'm a dirt bike guy that's coming to the car world!! HELP please! Thank you in advance!!
