Couple of questions

1. I have 4 fuel injectors I pulled from a 97' Plymouth neon
0 280 155 740 part #4669471
Saw they are rated at 21.1 flow something something(?)
I've been seeing 703 and 714 I think for the jeep but will these work for my 97' 4.0L Cherokee or did I just waste money?

2. The junk yard upgrade for the tie rod Is a zj v8 tie rod, well I bought both left and right tre's to replace but as I went to pull the zj tie rod I notice only one side has a tre and the other is a fixed ish side??? But the stock xj has one on each side. Am I getting this right or did I also get the wrong one?

2: the left tre is the one you want. You did get the correct one. Compare the zj tre to the xj tre and you will see a good size difference. And yes, the zj tie rid is a three piece ( inner, outer, adjusting sleeve)
