Truck 6.4

It is very tight, but they do fit. Not the most glorious job in the world to do, but, there's worse things. They in fact are the ONLY thing that seems to fit. 2010-2011 Jeep Grand Cherokee 5.7 manifolds fit, but, will be waaaay to restrictive on your 6.4.
Just want to jump in real quick, not trying to high jack but looking for clarification, 2010-2011 Jeep Grand Cherokee 5.7 manifolds are PROVEN to fit in a 74 Dart Sport? Plugging in a 2014 5.7 to my 74 sport and hav shears plenty say it won’t, and plenty say it will....
