It is the same water pump as my 69'. Look at the ear on the right (photo left) of the pump. That is to attach the alternator. The ear that is attached to the alternator now is for the power steering bracket. They used what they had to keep the car going. They even used washers as spacers. Don't believe the car had AC back then, it's an AC alternator. Also even back then I would think they would have used a fan shroud with more blades and possible a fan clutch. Lots of miss - match here. I also believe the sun - roof is a add - on. Of what the car is now, it is still a cool car and has potential to be Cooler. The right hand side mirror is also a rare option back then, if it is stock.
