Well, I finally went to a pull a part and I found 4 black interior 2GNTs (I finally scored big!). Tomorrow I'm going to pick up a dash and if possible, the kick panels and scuff panels. But there is always a catch when going to a pull a part. The driver's side door panel has a crack around the vent and speaker opening. Also, the fiberglass panel is cracked as well (easy fix). How hard is it to fix hard plastic pieces? For the bottom part (speaker cover and pocket) I was actually thinking about drilling out the plastic tabs on the back and attaching the gray piece from my current doors using screws in the factory tab locations if I can't fix the crack around the speaker cover. Has anyone tried this, or am I the only thinking this will work? After a good cleaning, I noticed the rest of the parts are in great condition, so I really want to fix the door panel and finally have a full black interior.

I thought about using a lower gray panel like you're describing on my black panel to cover the wholes in the speaker cover that the previous owner made to make room for speakers. I haven't gotten around to trying it yet though.

I don't know how you could patch the crack on the front, but you might be able to keep it from getting worse by taking a plastic welder and attaching some extra plastic behind it to keep it from flexing at the crack. Be careful if you try this, the plastic on the panel is really thin, so you could burn through. I used one to reattach the handle on my chopsaw when it snapped while I was using it last winter. Worked for a couple months before the pressure from pushing down on the handle ripped the patch off. A door panel wouldn't really have any pressure on it though.
