Broken Back Camera Glass

OK, I think I've looked everywhere here and on most sites and I'm still stumped. I just completed the iPod 5th gen LCD/Screen replace job. Went fine, but a nervous job indeed. I also purchased the Back Camera Kit thinking it included the cover glass (camera). Mine is cracked from a drop, and the pictures & video have blurred lines. Where can I get this small 1/4" dia. circle of glass? Do I need to re-open the case again (deal killer)?

Thank You, Great Products!
