I just got a great deal on a perfect 1998 GT.....drove it for one day before the intake cracked (it might have been cracked before?). This is my first Mustang, so I don't know much about my options here. It's driveable, but loses a little coolant when it gets hot. What will a stock replacement cost, or is there an alternative? How hard is it to swap? Any help i can get would be much appreciated.
