FYI Grommet replacement for Yonex Z-Force 2 (and alike)

Recently had to help a client replace the "in-line" grommets at the upper half of a Yonex Z-force 2, as it seem to be cutting into the string. 

Now for the shocking news - I called the local Yonex distributor as well as various local shops and they tell me to go order the replacement from overseas myself, as they would charge a processing fee for the item.

Why is it shocking, you say? 

If you try ordering it, the "in-line" grommet is not available as a single item. You must buy the entire set of grommets for the Z-Force2 at about USD$12 per set!!! This is before cost for shipping etc.

KUDOS to Yonex for this easy money making scheme!

So owners of the Z-Force2 and some models of ArcSaber/NanoRay/Voltaric be aware of these impending future expenses.
