APEX MI-008 Mini-ITX Case HELP!

[Usal]

Hi everyone! I have the APEX MI-008 Mini-ITX case but I seem to have broken my drive optical drive door. I got spare springs from APEX but I cannot figure out where it is supposed to attach. Would anyone with this case please let me know where the spring(s) go?

Did anyone here build the Official CustoMac Mini 2011 here: viewtopic.php?f=168&t=33412&p=209913#p209913 ?

I still can't figure how the optical drive door spring(s) work...
