Parts for Antec Cases

I have a Antec1000AMG Plus view case and you Antec guys out there know the purple fan holders for all the fan slots in the case.. well.. it comes with 3 but has four holes.. know it does have an adapter to fit one in the lower 3.5 drive bay for the fourth hole but i have cut that bay out for room for future water cooling.. so

question is "does anyone know wher i can order more of those click in holders.." i've looked all over thier web site and cannot find them anywhere.

sweet thanks
