Dan...

I did a trial fit last week-end with the truck mainfold and they were hitting the steering box and colum.....depending on the engine mounts you have, you may try to shimm with 1/4 steel plates..but one can not go too high because you won't be able to close the hood, so the last option we have is to get those headers....

Also,on an another tread from IMGTX, it has been discussed that the Durango offset bracket would do in our cars.....anyway, try it on , you'll see

So far, I have no promblems with the 904...
