why ask us, we cant see what you have there.
no engine,
stated,
some engine have high output alternator (60 or 75amp)
why not take it to the autostore, like all do and ask them
to match what was there,
what I do is look here, (usa cars) its free.
you see them all, aftermarket parts.
then see what matches yours, and makers
then see p/n ,
do you own research,
what does interchange mean, do you mean years used
or all cars its used on,, if yes, them find yours below.
say a delco, then go to delco dot come online ecatalog
and look up that answer, there, its there, for sure.
as is all makers, ecats. (shows used on x list of cars) and years.
