Hey Guys,
The LBS I go to sold me an older version of a Park Fork Alignment gauge (under $50.00) it's much heavier and more robust the the later version. The older one is a FCG-1 , the later one is a FT-4.
The one cool thing I like about the earlier tool is the fork blocks are removable.
The bigger knob on the FCG-4 doesn't look original, but I think it works much better.
