Thanks for the help folks. Since I have never had to replace the radiator, I am unsure what a 2 row, 3 row, or 4 row is, but at least it seems that I can order one without worrying about whether or not it will work in my stang. I am a college student with little money so I don't have to worry about performance upgrades anytime soon. (I do well enough to keep her running on my budget!) But summer temps over 100 degrees are normal around here so I think I'll go with the 3 row. Now if I can just find the money to buy it with! I gotta get it soon, I don't feel like me when I am not in the stang! I've been driving her for 13 1/2 years. Never owned another (drivable) car!
