And when most of the cars that we who come here were made the demand on an alternator was so much less than newer vehicles.
If I want a heavier alternator the newer "standard Mopar" alternators got 78a out of the same size package as some of the older ones that only produced 30-some amps.
If that ain't enough I'll have to go in the attic and grab one of my 100a versions such as what was stock on my cordoba I used to have and my fury that I still do have. I'll use up what I have here for $0 outlay before I go looking for something else
I have at least 1 set ( maybe 2, I'll have to dig in my pile) of stock small block 100a alternator brackets too.so I'm set.
