What Size (width) Fuses ???

For the life of me , I cannot recall what fuses I'm supposed to use in my '72 Coronet !

Of course I know that it uses the glass tube type ; however , there are different lengths of the damned things !
There's something like AGC and AEG or something ...
Can someone please clarify this for me ????

Once I garner this info , I'll have to :
- Write the proper name down on my car's notepad
- Come up with a way to simply remember the proper name

Thanks !
P.M. me if you wish :thumblef:
