Technical Do I need to remove the dash?

I have a '63 Pontiac. The fuel gage and the speedo don't work. It doesn't appear that I can remove them from behind the dash. Do I need to drop the entire dash to get these gages out?

 

Most GM vehicles from that time employed a "pod" or as we call it today, and assembly module. Look closely around all the chrome surrounding the gauge cluster. Removal of select screws should net the assembly loose enough to pull out as a single unit. From there gauge service can begin.

Quick edit:
Here a pic of a 63 but I don't know your model.You want to look above the gauges, below the pad, it may start with as few as 2 screws. Sometimes the knobs need to be removed as well depending on how the bezel is constructed.

You've already concluded it is the gauges, right? It is most often the sending unit in the tank or the speedo cable that goes bad.

 

Well I can't be certain about the fuel gage but I am able to get it to work by tapping on it from behind. The speedo I'm sure about. The odometer works fine and the speedo will actually work some of the time.

 

That's my dash. But I don't have A/C.

 

Looking at the places marked:

I can almost see screw holes here but not certain. I mean this in the most helpful way, this is where buying the assembly manuals pays off huge. Average swap meet price about $25-40, a bargain considering shop rates today. We did one about 6 years ago but I simply can't remember where the screws were. Was a quick pad recover in black leather.

 

If the '63 Pontiac is part of your life, buy a GM service manual for the '63.

 

I've maintained this car for 20 years without a manual. It's been a lot of trial and error. I don't know why I didn't just buy a manual back then. I suppose I never planned to keep it this long. It's on my list.

 

I just got on ebay and bought one.

 

I have to say that in all the years I worked at dealerships I seldom looked in the shop manuals.
That changed when I went over to the 'dark side': Porsche.
Our original manuals were in German, but the language was spoken at home, when Grandpa came to visit...I was by NO means linguistic in Deutsch.
But, as mechanical German is somewhat modular, and the illustrations were outstanding, I appreciated what the specs offered.
