Eh, I'm no stranger with ripping out various piece of interior. I had to run wiring for my sister's CD changer in her 6th gen Civic LX under everything, what a pain. Previously, I had completely disassembled the interior of my '82 Volvo 244 DL (for various reasons, including wondering just how far the rust had spread... it was very very bad)... and most of the interior of my '88 Volvo 740 Turbo, because the previous owners had a really poor alarm, wired really strangely. Virtually the whole front half of the interior had to come up. Turns out it was originally done by some "professional" garage in NJ, I checked the records they left me in the glove box, they got charged like $300 for the install...!
