This seemed to have little info on EXACTLY how the hoods and bezels were held on... so... here.
Once you get em off, it's up to you how you get the one piece triple gauge backplane out. I will probably just cut it out since I'm throwing it away..
First off... 'how the hell are they on there'?...
the hood has a notch towards the front

that notch clips over this post on the gauge face

'can i pull the bezel off first'?
No.
the hood has a plastic rim

that slides into a notch in the bezel

finally... 'how the hell do i get it off'?
you need to basically get a hook or some type of puller under the hood and pry it over the tab.
the rear is a simple clip tab that pulls up easily.

hold the rear up while you slide your puller under the hood and up towards the front.

you will want to line it up with the tab you are trying to get over.

make sure you get in-between the hood and the big flap that is attached to the bezel. then pull out and pry up with your hand.

you do have to pull out pretty hard to get it over the tab
once the hood is off its easy to see that the bezel is clipped to the gauge with the tabs... the top 2 are easy to get at. you kind of have to push the bezel down and tilt the gauge back to release the tab at the bottom.
try not to scratch up your dash or window.
