The armrests are each held on with four screws. I assume that your armrests still have the the mounting arms attached. The place where the pointy end of the springs go is often cracked. I have repaired them with a little bit of JB Weld epoxy.
It's been a while since I removed a center console and I'm not sure what screws it takes. I can include a bag of 'Boxster screws'.
$5 shipped if you want what is pictured. Let me know.
