I'm wanting the change the rear bumper cover on my '84 Camaro.
What's involved? Do the tail lights need to come out?

 

You will need to pull the tail lights. On the interior you will need to pull the back piece to pull the taillights and you will need access to both sides of the rear quarters at the bottom (inside) to get at the bolts out. Spare tire side is easy the other takes a little more work.

For the plastic clips at the bottom and top try to pull the center pin out to get them out (do not need to cut them etc. they are reusable).
