That's exactly what this was dude. THE exception.Here's a deep thought question. WHY are you buying junkyard engine parts where it would matter if an I4 or V6?
Junkyards are great for cheap parts that nobody but the OEM makes/sells, body and cabin etc, but for wear items that you have to replace due to that, it's time to seek new parts. If you have something specific in mind, I could be wrong......... There are always exceptions to the rule but most parts related to which engine a vehicle has, I want new not JY pulls.
One of the parts I grabbed was an electrical connector. It totally doesn't exist on the V6 version of my engine and there's no way I could've found it new if I wanted to.
