Alternator recommendation help

Hi guys,

Wondering if you can give me some advice.

My alternator in my jeep has died. I am thinking of using a duplicate part. Is this acceptable or a big nono? Realistically i just need the car to last a few years a averaging about 50 miles a day.

Cheers,
Hoonch

If using new parts it should be fine if it connects and fits.
Rebuilts are fine if using a quality rebuilder. They are getting hard to find.
