Default [Q] Screen replacements?

I was just curious, as having just cracked my screen.... (seriously just fixed the stuck power button issue, and no i didnt slam it against the table)
If i were to buy this kit: http://www.amazon.com/ProKit-Samsung...een+repair+kit
Would it work for my SCH-R530u? Or do i need to find an OEM glass for my phone?

As always all help is appreciated, You guys are awesome.
