try performance-pcs.com and silverpcs.com both have some replacement parts for L-L. I never get responses from the email or online form messages I've left to places like L-L, Silverstone, etc. Use the phone number instead: 886 2 2451-3000 - I haven't been able to find a US phone number either. Perhaps if those two resellers can't help you, then there is no help. Yet another reason to avoid L-L cases. Beyond that, you'll have to have a local sheet metal shop make one for you or make it yourself.
