Tail light madness.

[auburneduprof]

Just bought a clone of my 2002 V70 for my son (it's actually a 2001, but same color and looks identical). The only problem with it was a bulb position sensor light and a check brake light. When I got bulbs to replace (right rear brake and reverse light) and tried to install them, the two sides of the bracket holding the bulbs in, which were already split fell apart. That explains why the bulbs were fine but not working. Can you please point me towards what I need? Do the bulb brackets(?) or whatever they're called come with a used tail light? If not, what are they actually called and where can I get them? How do I remove the tail light lens assembly?

Thank you in advance- need to solve this problem soon as the local authorities will not have a sense of humor about a non-working turn signal.
