i've found them incredibly difficult to find. I managed to find only one car with the 703s last time.
Make sure you give them a good cleaning before installing them.

I went thru 10-12 cars and was about to give up when I found a set. Since that gave me 4, I kept looking and found several more sets. It's not just neons. Check the chart I posted previously in this thread.

i know. The junkyard i went to had tons of chryslers and dodges on that list. I went through every single one - only one had 703s.
Luck of the draw i guess. I'll check another JY next time

Put a 99+ intake on there and you will really notice a difference.

The injectors are also different for a 1999-2001 Cherokee.
87-98 *703 injectors
99-01 *784 injectors
This chart should help:
