Harmonic Balancer Question

Yeah problem with pulleys lining up, there is about a 1/4" of difference from where the bottom pulley should be (too far out). I am having to switch everything over from a 1969 setup to a 1970 setup so I can use the passenger side water pump outlet for the newer style high flow water pump system. Can you measure the fluidmper thickness for me? Also what is the measurement from the water pump snout where the fan bolts on to the front of the damper? If you can get these I will be forever greatful....thank for the help.
