Is it possible to replace just the glass lens of the SGS2?

I am wondering it is possible to replace just the glass lens of the SGS2 and not the LCD? I have a cracked glass and the LCD is working fine - no dead/leaking pixels.

I went on amazon and ebay for replacement parts and found two different parts:

1. Around $10 but is just the front glass outer lens screen cover;

2. LCD and Touch Screen Digitizer (outer lens) for $140.00

Since my LCD is not damaged, I am hoping to get just the replacement outer glass lens.

After watching several videos, everyone is using the Frame Flex part (LCD plus Touch Screen) and no videos are showing just the replacement of the cracked front glass.

Is it possible to just replace the cracked outer glass?

Thank you in advance :)
