I damaged an injector when I changed O-Rings, don't ask, just say I damaged it is good enough.

So the last couple days my Renix was running like crap.
So I had some Ford Hitachi E7.. injectors laying around and thought I've give them a try.
That did not work so well.
The XJ ran like crap, popping back, and just missing and would not accelerate with full throttle.
So when I pulled the OEM injectors I noticed one looked slightly different in the port end so I set it aside and pulled an injector from another 4.0 rail and added it to 5 original ones and poof its all happy again.

I was thinking of ordering a set of Bosch 19lb injectors off ebay with the 4 fuel openings and trying them, but now I'm not so sure.

The ones in question.

So what do you all think? Buy try em, or is it a waste of time?
