Got the 1st gen lamp and it doesn't quite fit properly, so there is that, I cut a couple tabs off and it wedged in pretty good, I am thinking some hot glue is in my future. Also the plugs ARE different, so if you get a headliner out of a parts car BE SURE TO GET THE WIRING! I plan on soldering and custom attaching mine up since the wire harness can't seem to be found. Also the lamp that I got has map lights AND the center light so I don't think it's the one for that spot but since it "fits" I am going to run with it. Pics once the LEDs come in.

"2nd Gen problems"
I've spent too long looking into the abyss. It's starting to look back.
