6045 Digitizer replacement?

Hello all, looking to replace the digitizer at some point. I have a lot of scratches already. Does anyone know if the digitizer part alone would be sufficient, or is it fused to the LCD thereby requiring LCD be replaced as well?

Figured someone here knew by now, can never trust the eBay sellers, hehe!
