Fusible link question ?may have to make a correction...

I've done my own wiring, starting years ago.
At that time I placed a 60 amp fusible link
Right off the alternator. Well, I actually had a 37 amp alt
I found an 80 amps square back and got it on my 360.

Now I have an 80 amps alt and a 60 amp fusible link.
You need at\least 80 amp link. 100 is better.....
