If you do not have the timing chain cover, radiator or water pump, go with the 70 and up style set up. The advantages are as follows: (1) The timing chain cover has the timing marks on the driver side of the vehicle. (2) You can use the aluminum water pump. (3) All of the parts (water pump, radiator, timing chain cover, radiator hoses) are easier to find and less expensive to purchase. My favorite radiator configuration has the inlet near the radiator cap and the outlet on the lower passenger side of vehicle. Retaining the 68-69 inlet position provides more room around the carb return spring bracket. The routing of the 70 and up inlet position routes the inlet radiator hose over the carb return spring bracket.
