Finally got everything wrapped up. Just wanted to post some 'after' pics and say thanks for all the tips and the great write up! I took a lot of pictures of the process so if anyone wants more photos, just let me know.
I have a 2005 Sport so I'm posting a pic of the gauge cluster board 'cause it's different than the newer sports (Darkie's photos) and the board from the Limited, posted earlier in the thread. 20 LEDs still worked for my swap.
I also tried out a little mod I found. It requires peeling the LCD film (which makes the LCD read out visible) off the face of the LCD glass. I just used a decal scraper and carefully removed the film, then used bug and tar remover to get rid of the remaining glue. Then you apply 'reverse polarization LCD film' to the glass, making sure all the air bubbles are squeezed out. What you end up with are LCD readouts w/ a dark background and a white readout.
