I'm really beginning to wonder if you know what you are talking about, because that 3 bolt gasket has nothing to do with the water pump, just saying.
sometimes i wonder too lol
i'll take pictures if you want me to explain better.
#13 water pump is tall(at least the back part)
#14 is the gasket behind the water pump
to get water pump out of the way to access gasket #14 you need to move the water pump forward. It's held in place by rear coolant tube and #10 part, the issue is that you have to wiggle it out and i was not able to do it without removing #10 from #7
That's just my experience, it all depends on what water pump you get
