8700g Outer Casing Hardware Issue - Screw holes Stripped/Case Coming Apart
 

Hi. I have a Blackberry 8700g. I noticed that on the side where the trackwheel is, where the 2 halves of the outer casing come together...well, it is coming apart. you can press it in and it kind of pops back to where it was, with a little "click."
being the mechanical engineer i am (i am actually a mechanical engineer), i opened up the battery door to check to see if the 3 main torque screws were lose. to my surprise, the holes were all stripped and no matter how much the screws turned, they would not tighten.

my conclusion is that if i am going to fix this problem i will need a new outer casing (most likely will purchase from ebay or some other place online). will i need any other replacement parts too? if someone could help me out with this issue, it would be greatly appreciated. i am good with fixing things, but i am new to the blackberry world. WOULD I BE ABLE TO BUY A SLIGHTLY BIGGER TORQUE SCREW...WOULD THAT FIX IT? (sorry for the caps, but i wanted to emphasize this question).

so yea, the case seems to be lose on one side, and the sockets where the 3 main screws (that are exposed when you take off the battery door) are, seem to be stripped since the screws will not tighten.
