The Sylvania site has this for the instrument lights on a 69 GTX:
Instrument-general
1893
194
53
57

So which ones do I use on my instrument panel?




Well the GTX of that year uses the #57 which is a brass base bulb with push and turn bayonet lugs.

My Duster has the "grain of wheat" all glass bulb which just pushes in the socket.

I'll try to dig up the paperwork on the bulbs today and post the info.

I'll note though I do not like how hot the headlamp switch gets running the new dash bulbs and will look into the cooler LED's when time permits.
