help for installing new tail lights on my '92 civic hatchback

I own a 1992 honda civic hatchback and I would like to know how to install the new tail lights I just got. I didn't have much trouble with the two lights on both sides of the "tailgate", but the two on the outside by the left and right quarter panels are giving me a little trouble.

When I installed my tail lights on my 92 DX hatch I first removed all the screws I could find in my "trunk" area. Then I pulled back the interior panel and had my friend hold it while I squeezed my hands in to unscrew and screw in the new lights. It also made it easier to remove the plastic panel on the inside of rear of the hatch, because the panels you have to pry back and underneath that piece. Sorry if that sounds complicated, it's just hard to describe it in words.

Be careful when puting in the aftermarket lights because they dont always line up. Just make sure you dont damage the threads.
