Fuse constantly blowing out?

I have a 1979 Firebrid and a few days ago the "STOP" fuse went out causing all my lights to go out and the radio. So I replaced the fuse again and now its out again. Is this a short? How would I locate a short? How can I address this problem? thanks! People where saying to look at the tail light first for a short but i just wanted some other opinions or tips. Thanks!

Sometimes when the bulb blows the wires inside cross so I have to agree with whoever told you to check out the tail lights

try this

The Stop/Haz fuse must have been tapped for the radio. It is normally not used for the radio as there is a separate fuse for the radio. Depending on the radio it could be overloading the circuit. Disconnect the radio from the stop/haz fuse.
The stop/haz circuit passes through the turn signal switch. This could have an intermittent short which would cause the fuse to blow.
Start by inspecting all the wiring and components of the circuit. Namely the stop lights and front turn signal lamps. Also the stop light switch and the wiring around the steering column.
As a test; remove the fuse. Then connect a dummy load across the fuse terminals such as a headlight bulb. This will energize the circuit but if the short occurs the bulb will go to full brightness giving an indication of where and when the short occurs. So as you proceed through operating all the parts of the stop/haz circuit you will observe the brightness of the headlight bulb until the short occurs giving full brightness.
Then repair the component at fault.
See attached schematics to test various components of the circuit.
