Drill 17 dimple 19

On 25-04 step 1 Vans is telling you to final drill #19 holes to #17 and dimple. Is the reasoning behind this to negate cracking on the dimple (found through research) or should I be dimpling this hole with something different then my #8 dimple die?

Thanks,

Jim

Yes, that is correct.
