AL-320G Tailstock high

I have just installed a new AL-320G lathe and a dial indicator on a drill chuck arbour in the tailstock shows that it is .05mm higher than the headstock. I believe that they are made slightly higher to allow for wear on the bed but is .05mm too much? If so, should I remove some material from the base of the tailstock or is this not significant enough to worry about? Will this difference affect drilling centre holes with the centre drill chucked in the tailstock? If material should be removed what is the best way to do this bearing in mind I don't have a mill or surface grinder etc? I have flattened the soles of metal hand planes using wet & dry paper on glass. Would such a method be OK for the tailstock? Thanks, Kevin
