NOS AMC DELCO-REMI V8 FSJ ALTERNATOR. THIS SHOULD FIT MULTIPLE APPLICATIONS LIKE WAGONEER, CHEROKEE, J10, J20. THIS WAS TAKEN OUT OF AN AMC DEALERSHIP. SO I AM NOT TOTALLY SURE WHAT ALL THIS WILL FIT. THIS SPINS REALLY WELL. THIS COMES WITH THE BOX. 8125155 IS THE PART NUMBER. THIS IS IN GREAT SHAPE. PLEASE SEE PICTURES AND ANY QUESTIONS PLEASE ASK.
