Honestly it is very easy.
One piece of advise I can give is to pull the "padded" part of the dash surrounding the cluster before pulling the cluster.
People will say, naw just pull it out. It's only a few screws and the padded part comes right off. with it off the cluster is way easier to get out and you won't stratch up the cluster cover either.
as for the bulb, it's not a big deal. Also the cluster simply unplugs from the connector that is in the back of the dash. So it is very very easy to pull the cluster.
So pull the cluster take the black cover or facia off the dash. The part covering the stereo ect.
NOTE: Be carefull when you undo the Headlight/dimmer assembly. They are a pain to unplug and the connector or dimmer mounts can be easily broken. Don't fret though you can use silicone or liquid nails to hold the dimmer in place from the back.
Then take out the screws on the heater controls. NOTE: The hex head bolts. "usually" If your truck has been apart before who knows whats in there. The ones on the cluster side can be a pain to get to with a socket. I changed these two screws out to philips heads for ease.
Then if you have factory pocket or radio you can get to the screw hidden behind the HVAC control.
You have to move the radio/pocket out of the way to get to the top cluster screw. There are only 4 screws holding the cluster in place.
FYI, word of caution. You may need a 5.5mm socket. This is a rare item in most socket sets. So if you find a 5mm and a 6mm won't fit, that is why.
Again like I said, you never exactly know what screws are back there unless you know the trucks history since new.
I had to have the following
philips screw driver.
