Yes speaker sizes have been standardized since before the old tube truck radios
A 6x9 is what the radios use in the old trucks
The ford speakers are identical
The radio manufactures don’t make speakers
You buy a speaker and stamp “gm original parts” or fomoco onto it to make it your own lol
However if you want the oem style speaker and you have a broken rotten one they can be rebuilt to perfect original specs to keep it authentic
I have some photos in other posts about some of that kind of work
