Water pump fitings

[1968RRTEXAS]

hello everyone, trying to figure out the right fitings and locations for my water pump. The holes are different size. I looked on 440 source at the fittings they sell and they are both for 5/8" heater hose. Any help is greatly appreciated.

Water pump inlet/ outlet

Is this what you are inquiring about?

So I ordered the fittings off eBay and the seller sent me a email asking for year make and model to be sure it was the right part I needed. So I replied back and I'm confused again. The owner of the eBay stores said that the water pump I have wont work because my heater box is pre 1970. Which makes sense since both of the copper fittings coming out of the firewall are the same size. So now my question is. Do I need to get a correct water pump (don't have any money) or get a brass adapter fitting to correct the water pump fitting size difference.

I would reduce it. Fitting should be at Home Depot.
