idk about the 94, but in my 92, the rear brake light was only held on by 2 bolts that were easily accessible. the speakers were a pain to get out, i had to remove the deck on my 92, the seat belt guides were a pain and so was getting the deck around the top anchor point, and also you have to remove some pins (at least in mine) that held some of the back deck on, but it was a really tight squeeze anyway i tried removing it. The speaker installation after getting it all out was a breeze thought

. and the improved sound makes it kinda worth it. got a few cuts and stuff, cause the metal can have some sharp edges back there. i hope this helps at least a little.
