vintage air pulley alignment

with the brackets and compressor mounted, the most forward pulley on the compressor seems to be lined up with the water pump pulley's middle flange (between the two belt grooves). in order to engage the crank add-on pulley, i'll have to move the compressor about an inch forward. i can use spacers to move the brackets forward, but i'm concered about vibration. anyone else have this problem?
also the compressor has top-side ports-will the hoses clear the hood?
thanks
