Need help with memory installation

My MacBook, which I purchased 2 years ago, currently has 1 gb of memory. I understand the max I can take it up to is 2 gb. I ordered 2-1gb Ram modules to replace my current 512mb memory modules. My user guide says to remove the battery and then... "Loosen the three captive screws that secure the L-bracket, pull out the long end first to remove the bracket, and place it to the side."
When I remove the battery, there is NO L-BRACKET. I can't find any other instructions on the support page that shows how to upgrade memory in a MacBook without the L-bracket.
Any suggestions on how to install the new memory myself or should I just make an appointment and take it in to the nearest Apple store and have them do it?
