The easiest way to gage the fork is to remove it from the bike and place it, via the sreerer, on a relatively flat surface. A vee block is perfect for this. Then one can compare each blade/drop out to the surface, the crown and the steerer.
For the second time in a week I'll provide a link to a post I made a year or so ago about checking fork alignment with simple tools at home. Andy.
