Help with reassembling nano 4th gen

I have successfully fixed a broken clickwheel cable, but am having problems regluing the clickwheel plate to the case. What is an alternative glue? The ribbon cable from the clickwheel won't readily fit back inside the case once reconnected to its white socket. The cable won't push any further into the base of the iPod. I don't want to push too hard in case it breaks. Finally, can the hold switch cable (which was broken) also be replaced? It seems to go to the main PCB without a plug?

Thanks
