Guessing this is what you need:
LCD/Display Assembly Service Kit X046J 8.9 WSVGA LCD service kit,LED,Truelife(Incluede LCD panel, LVDS only cable, LCD left/right rubber)
Don't know how much it costs from Dell... search around for that... seeing $170 USD? If that is the case just buy a brand new Mini from Small Biz for $199 and transfer your working drive into it and you'll be back in business. Then gut the rest of the busted mini and sell for parts and you'll probably end up not being out much cash.
