Have to disagree somewhat. My gen 2 needed offset shafts to get the caster right. Was told years ago the frames tend to spread over the years and the offset shafts are needed. Some of this will depend on how "plumb" your graft is. IMO, manual steering will be OK with 1 1/2 to 2 degrees while PS will feel better around 4. Your good alignment guy will steer you in the right direction, pun intended.
