Better Bigger, Alternators mean you are not beating on the battery as much , if you take the car for longer cruises a 65A might work OK.

there are plenty of options in the 90-130A category these days.

If you use a high AMP alt remember to use a suitable BAT+ connection from the power output section of the ALT to the battery lug/post so you dont weld anything accidentally.

like 10GA or better.
