You have to remove the trunk carpeting on the sides and the front to bolts.

for the UCF10 the bolts are located here:

This is the image from my 1998 manual.

I shoudl say bumper COVER, not the actual bumper. From that diagram I still dont understand if the bumper cover is bolted thru the body-into the trunk area or just can be unbolted from the exterior of the car. Not a very good exploded diagram.

I think the two on the far sides are under the taillight. not 100% sure, but they are easy to take on and off so it wouldnt hurt.

thanks. I have a custom trunk setup thats a bear to take out, want to avoid that lol. tailights are easy to access though .

To remove the cover just remove the trunk carpet on the sides and the one right under the trunk latch and you will have access to all the nuts inside the trunk. Also there are screws in the rear wheel well.

I took off my rear bumper and it wasn't that bad.
You need the car in the air with the rear wheels off.
There is a screw(or two) holding the fender liner the the bumper on each side
There is also a nut holding the corner of the bumper to the body just behind the fender liner
Then there are 2 more bolts down the flanks of the bumper as you make your way to the back corners, these are accessed from inside and would be under the side flaps of the rear cargo cover.
There are 2 nuts per side which have the be removed from the inside that hold the bumper to the car where the bumper does that odd step up on the sides. You will need to remove the carpeting and anything that might be blocking access to the back corners.
There are 6 nuts that hold the bumper to the body where the trunk lid meets the bumper. Again you need to remove the trim and carpeting to get to these. They are all hidden for direct sight in little pockets, you might have to bend over the bumper and head down into the trunk to see them.
There are also all of the bolts and push tabs that secure the bumper to the lower shields and trim that need to be removed.

The rear corner nuts and flanking bolts are probably going to be your biggest obstacle to get to having seen your trunk setup.

I will say that when you are taking it apart, becareful as these nuts and bolts are very prone to rust and are common to snap off.
Also when putting it back together, use some silicone on the either side of any hole into the trunk. Once the bumper is removed you increase the odds of leaks coming in through the holes, especially in the area where the bumper meets the trunk lid. Plus the silicone will sellout moisture from killing the nuts and bolts again!

If that didn't help, I can snap some pics of the bolt locations since my trunk is half apart right now in prep for my air install.
