Technical Fiat 128 1979 Alternator

[CtrlDeviant]

Hi im new to the forums as i just bought a 128 1979 Sedan 1.3L im enquiring about an Alternator as the one i got is knackered, is there a sepcific fit or can i use a universal fitting, what are the Requirements for fitting a new one can i take one from a newer fiat ? Im not very tech savy so don't know much about these sort of things, I need one thats got a bit more juice 60+amps not using the car for racing only daily driving, keen to get a sound system put in too if i can get the right part.

Your help would be much appreciated . Thanks
