I'm probably missing something obvious. Putting together a 1965 260 the harmonic balancer lines up with the generator and the ac lines up with crank but water pump pulley does not. Bought this car it was apart built a different 260 used the timing cover from the second 260 I bought. I have measured both timing covers they measure the same height. Also measured 2 different water pump heights both measure the same. Don't know if this might help if I put 3 5\16 washers it lines up pretty good but I know I shouldn't have to do this. Any body run into this. Thanks
