The gasket and adhesive kit came with a great set of components. However it's not clear when and where they are put. Would be nice if iFixit had notes about these for reassembly.

I just flooded the battery space with rubbing alcohol and let it sit for a minute. Then the battery more or less lifted out. If you still think you need it a smaller suction cup or even dental floss to run under the battery may help.

So where do I get the back panel replacement part?
