Where I can get the glass only part for the digtizer?

As stated in the title, does anyone know where is the front glass part for iPad 2 and above iPads without the "true digtizer"? There are tonnes of them for the iPhone 5, but I could not find a single one for iPad 2 and above. The closest I could find was for iPad 1. (http://www.ebay.com/itm/Mid-Chassi-Mid-F...)

And yes, I know you may say its very hard (and indeed it is), but the glass has already been removed from the "true digtizer". And this is just an experiment. (I have already fixed my 2 iPads that I have broken three times with new digtizer, and I got some broken spares lying around. The old digtizers are still working.)

Any links or help (P.S. no shops please unless in Singapore) would be greatly appreciated. :)

Sorry if I have ever posted in the wrong place, or broken any rules, I have unintentionally did it a lot of times in a lot of communities. :P

Cheers.
