I recently did this on my ST... Just remember to make sure you put all the screws back! Got all the bezels on, realized I didn't put 5 screws back.. Took it apart again. Second time around, I had 3 screws left over, from something I had to take off to put the other 5 in.
Suffice it to say, third time was the charm! But I also agree, change all 6 bulbs at once; my mouth was agape when I could finally see other things other than my speed at night.
