Request Script: Quest Custom Headgear with Preview

[Cebols]

Hi All,
I would ask a favor for quest custom headgear with Preview.

All Custom Helm need same item
All Custom Aura need same item
All Custom Wing need same item

Preview look for Helm start from view 2001-20100
Preview look for Aura start from view 2101-20200
Preview look for Helm start from view 2201-20300

Thank you in advance...
