Taking out the ramps (for the first time) is a bear; its required to change all the bulbs in the pop bumpers, and to change all the rubbers. Be careful with the diverter shaft. Double check every area, as you will undoubtedly have one black rubber on a impossible to reach post after you switch everything to white rubbers and put everything back together, and you'll notice it every time. Ask me how I know, haha.

I would HIGHLY recommend swapping to led's for the above mentioned reason; there are a lot of bulbs in this puppy (like 140ish if I recall from when I did mine), and it has a tendency to get pretty warm with standard incandescents. I swapped and replaced the GI pins in mine about a year ago, and they still look as good as the day I replaced them. Zero yellowing/browning.
