I had both sides on as I was setting my 318 in place. Didn't go any further because I would have had to basically bolt up the trans, and didn't want to do that twice. Looks like the top of the steering box will be close. Also looks like the trans dipstick might be an issue. Anyone running them? Vs the stock manifolds 1.6" outlet, the 2000 magnum has a 1.9" and a smoother flow, plus no heat stove butterfly. Should be a pretty good increase and I love the sound of my 2000 Dakota R/T, which should be similar.
