will a 1968 belvedere radiator fit in my 1967 belvedere I know outlets little different

Even if it bolts in you may find yourself having a cooling problem as the system is designed with a smaller inlet hose than outlet to create a pressure vacuum if you will on the inlet. This is not specific to your vehicle but is an important part of the cooling system that is often overlooked by fellas anxious to get there hot rods on the street (im not saying you're one) and wonder why they're always overheating. Not having the engine set at the appropriate angle to the the level of the car on its wheels is another big one
