Made a Saturday trip to pick n pull and managed to get 4 703's I guess i'll have to make another trip in a few weeks. I hope by then some more Neon's take a crap and end up there.

So they only have 4 injectors and we have 6 so that means I have to find 2 differnt cars to get them from?

stock are 1 hole
703s are 4 hole, which allow for better fuel atomization and better throttle response
think of the difference between a squirt gun and a mist

You have to find the right 4 banger even in the years that said had the 703's. I was coming acrossed 740's in alot of neons and stratus with the 2.0 engine 95-97. The 740's look the same but shorter.
Just picked up a set of 6 - 703 injectors. My '91 XJ currently has orange-top injectors. Are the orange tops stock? Or were they upgraded previously? I have not taken the time to pull one, and probably won't until I am ready to install the upgrades.
