I replaced mine, The bottom screw is accessed by removing seat, as far as top of panel, it just slips under tank console. Using 1/2" wrench loosen top acorn nut near speedometer, no need to take off entirely. You can now move console enough to slip panel under. I went with Harley Skull Leather panel on my Night Train.
I just did this last night. I too added the skull panel to my 2000 night train. The only thing I'm not happy with (this is real picky), is the panel angles into the instrument panel which dosnt conceal the ends of the weather stripping that the orginal did. Installation is a cinch, and it looks great too.
SDA, I bought the same piece that matches my dash as well. My complaint is that the fu*king thing is plastic!!! Scracthes way to easy and i am now going to replace both of the peices with chrome (metal). Was annoyed when i realized what it was made of.
