Ok, a 69 Water Pump and a 70 Crank Pulley, I'm pretty sure those don't match together.. 3-bolt was used into the Early 70 Cars, then switched to 4-Bolt. the reason I say they don't match is that the Pulleys have to work in conjunction with Alternator Positioning, and the brackets mount to the Water Pump. Is your Pump pulley a C9- or a D0- If it is C9- you could switch out your Harmonic Balancer and Crank Pulley, and if it is D0- you will probably need a 70 Water Pump. IMHO, It is hard to tell in the pics, so this is just a diagnosis based on what I have heard. Does your Radiator Hose Flanges match the position of the water pump's? ie: Same Sides, Top and Bottom? Now I'm not sure if this is a 69 or a 70 motor, the 69 Orig. Water Pump is usually the determining factor, as that would usually be gone. .
