Housing / clips to hold ram

I upgraded the ram in my mid 2010 macbook about a year ago. Recently screws worked their way loose and computer has been crashing randomly. Opened up the back and found that the housing / clips to hold the ram in place seem to be broken. Can't find anywhere on line to buy a replacement and in fact don't even know what that piece would be called. Warranty is obviously expired and would like to avoid a super costly repair. In addition, i live out in the sticks and the nearest apple store is several hours away. Advice / help greatly appreciated!
