Thinking of buyingan ebay radiator. My GP is a '97 GT. I notice the GTP radiator is the same dimensions except it's 3/8 inch thicker (1" as apposed to 5/8") and weighs 3 lbs more. Will it fit and mount OK in my GT? I'd like to get the added cooling for a few bucks more if I can. It gets real hot here in the summer time.
