Did you removed the license plate light? That is also hold the panel up.

Remove the license plate itself. Behind the plate are two hex head bolts. You gotta remove those as well. Then the fascia panel can be removed, and you can unplug the reverse lights and license plate light.

Yup - I removed the plate and the 2 little hex head screws, but the fascia still didn't seem to want to come off without a lot of force, so I stopped before possibly breaking something. That's when I decided to check with you folks here on the site.

So, if there's no hidden nuts down inside the trunk structure, I'll proceed cautiously from this point. Thanks very much for the replies.

There are two more nuts outboard of the license plate that look just like the nuts along the bottom of the fascia. The trunk has cutouts where you can get to these nuts. I think one of them is right next to the keyhole. The other should be in the same spot on the driver's side. They're not really hidden, but not glaringly obvious either. Do you have these removed?

Nope - that's exactly the information I was looking for, though. I figured there were 2 more nuts to be removed, but I hadn't found them yet - I was rushing a little bit, because of an appointment. Your reply has been extremely helpful - I'll take my time and do this properly now. Thanks.

Just to follow up - I just finished getting the Marauder fascia and PI taillights installed and they look GREAT! It took a few hours messing around with the lock tumbler and various bolts and washers to get the depth right for the Marauder fascia, but it was well worth it. It vastly improves the look of the GM from the rear. Of course, now absolutely everyone who comes up behind me will be certain I'm a cop and sit in my blind spot (not that they didn't do that before) - but I don't care. This really cleans up the look of the car.

Thanks to everyone for the advice - I knew exactly what I was getting into before starting - very helpful.

Sorry for the dumb ass questions about the "hidden" nuts holding on the fascia - once I actually looked in the right place, they couldn't really have been more obvious. Duh...
