Gotcha, thanks guys. Did some wrenching this weekend, as well as tackled the stereo situation. #4 plug with headers it a huge PITA, I could just about get it out but my plug socket was getting wedged on the header. Ended up using a ratcheting wrench on it. Thankfully I messed with that one first, and it took me nearly an hour to get it out. The rest went fairly quickly. I'm waiting on some plug wire organizers to get here, the factory ones were brittle and went to pieces when I removed them. I couldn't install the new coil wire, the factory coil had some sort of clip on it and I couldn't figure out how to get the new coil wire through the plug to clip it on, so I just reused the old coil wire. I've got a new distributor cap/rotor coming along with a new coil, so that should resolve that issue. I went with Motorcraft plugs/wires and MSD coil/cap/rotor. Hopefully those are OK - they had good reviews on LMR.
Stereo - back in the day, this was a pretty high-end system. Eclipse HU, PPI 6-channel amp (made in USA - back before they were bought up and started making shit) - these are going for $400-1800 on eBay at present. I'll probably just reuse it. The subs (2 12s) were Soundstream Reference, again, made back before they went to shit. MB Quart components up front in the doors. The tweeters are gone, so I'll find something decent to replace with. I spent the better part of 3 hours yesterday getting the sub box out - I'm guessing it was assembled in the car, as there was no way I was getting it out. Ended up cutting it apart with the jigsaw and a saws-all. That was quite an adventure.
It looks like the keyless entry module is gone. I can see one plug, which I saw a video that referenced it being how you programmed new remotes. I was unable to locate the other plugs - I believe there are two that plug into the module which run to each door. I need to dig back in a little deeper I guess. I was tired of messing with it honestly after the sub box adventure.
Pics to follow.
