Help Failed Emissions

ELSC

I just inherited a 93 SC and got the emissions tested and failed.
The exhaust looks to be original and the cats do rattle(I think it's the converters) My question is where do I start? This is the breakdown of readings. HC(PPM) Limit 79 emissions 111, CO Limit .42 emissions .63,and the bad NOx PPM Limit 921 emissions 2480. I would like to fix this asap. BTW I owned this car 2 years ago and put new plugs(Motorcraft) and wires (Magnecore). My father in law had the car and put about 6000 miles on it in the past 2 years. It also past emissions in NY 11/06. Any imput would be appreciated.
Thanks
Brian
