I have always just taken out gauges and just rested it on steering wheel, but you could probably reach it from backside. It would require a small hand and be difficult.
If you still have the original cluster, this would be a good time to look at upgrading it. In the 70s they used a plastic compound that degrades very badly. If it's original, it will likely crumble when you pull it out.
I'm not sure when they switched to the new plastic. I got my replacement from a mid 80s van. The vans used the same instrument cluster as our trucks well into the 80s.

In 1975/79 they used a POS instrument cluster back made of a composition material that degrades very badly. If it's original, it will likely crumble when you pull it out.
I'm not sure when they switched to the new hard plastic cluster back(1981). I got my replacement from a mid 80's Econoline van.

OP's "About Me" profile: 1974 F100.
1973/74's did not use the same POS instrument cluster backs that could TURNTO DUST (before your very eyes!) that 1975/79's did.
1981: FoMoCo introduced hard plastic cluster backs for Econolines, these were also the "service part replacements" for the original POS backs.

Do yourself a favor....while you are replacing the bulbs go to led bulbs. I can actually see my gauges at night now. The pic. below was taken during the daytime. You can get the led bulbs in different colors. I went with green as you can see.
I too went with LEDs. I used Superbright white and am still impressed with how bright they are and how well I can see the gauges now.
As for installing them, I’m still just flexible enough and stubborn enough to change them out with the cluster still installed. Didn’t even hardly cut myself!
Columbia1spring I apologize for the highjack but I too am interested in the Dash-light upgrade.
Dekeman and Shortbox4x4, tell us what LED bulbs you used. If you have the brand and/or part number please post. Thank you, highjack over.
I upgraded my dash lights W/LEDs. Problem is I can't recall the company, but I kind of remember is was something like "HIPO". I'm also very happy with the visual improvement the LED bulbs made. Here a link that may help: https://www.superbrightleds.com/vehi...=794&year=1977
Surprised it hasn't been said, but it's only about 6-8 screws to remove the gauge cluster. Literally takes 2 minutes to remove. Just be careful about scratching the plastic lens, the corners on the metal dash can really scratch it up.
