A 275 or greater width tire on an appropriate rim should fill the front fender well nicely. No need to change the suspension arms. An answer to a question that wasn’t asked.

To create this change without changing wheel offset, you would need to have longer control arms, as pointed out above, or move the mounting points for the existing control arms out from the vehicle center line. Right now, no one is making bolt on upper and lower control arms for classic mopars that would accomplish this. Relocating frame rails for this type of benefit is more work than the benefit would create. Can it be done, certainly, but it will require fabrication of custom parts or adapting the mounting points to allow other types or arms to be installed. It is not unusual in the oval track crowd to have upper and lower control arms available in half inch increments from 5 to 12 inches in length. Adapting these is possible, but no one has done it that is hanging out here.
Another advantage of doing the longer control arms is that you create larger arcs of movement, which creates less dramatic change of angles as the suspension cycles. It also requires much more positive offset on the wheels to keep the tires in the same space. This high positive offset, which is common in modern cars, creates a negative scrub radius. In stock form, our mopars have a large positive scrub radius. Negative scrub radius provides decreased torque steer effect and more stable steering response and stability compared to positive scrub.
As pointed out above, A body lower arms are a fractional bit longer than B and E body arms. No stock style longer upper arms exist, but tubular arms with built in additional caster may allow you to offset the upper bushing enough to match the longer A body arm without getting radical camber and messing up your caster.

From a handling standpoint on track width: 1. EVERYTHING effects everything else 2. Like tires, and it seems very few agree with me, in that over past decades tires have steadily gotten wider, with little end in sight, and wider track is always better, biggest downside is aero drag, and that likely on comes into play significantly at over 100mph 3. It also looks cool

A 275 or greater width tire on an appropriate rim should fill the front fender well nicely. No need to change the suspension arms. An answer to a question that wasn’t asked. But it’s an answer to his objective (better handling) Which car has more grip?: 9” treadwidth tire on all 4 corners with 60” track width Or ? 8” treadwidth tire on all 4 corners with 62” track width. All else equal of course. . . . Dodge offers a wide body version of the Charger & Challenger. . Every widebody comes with 305 (12.3”) wide tires vs non-widebody 275 (10.9”) wide. The widebody’s don’t come with the same smaller width tire.

Tire width and track width are independent of each other. Regardless, wider is better for both, independent or not., What is your point?

As stated in the third post, he wants the tire sidewall closer to the fender to give a different look. A wider tire or even more offset accomplishes that. If you want to keep the 205-70-14 on the front and redesign the front suspension to get it closer to the fender, feel free.

I'm not sure about that, "Tire width and track width are independent of each other." is pretty hard to surpass. That pretty much sums up the fact that you know nothing about the subject at hand. Explain to us how, without changing anything else, a change in tire width affects track width. Even better, explain to us how a change in track width changes tire width.

Dude, you are stating the obvious, and don't seem to know it, which in my book fits somewhat the use of your term ,"irrelevant" But if you insist, I'll repeat my self to reinforce MY POINT, "wider is better for both, independent or not."

Spacers are OK if you just want a little bit...like a 1/4”. The problem is they load the bearings and ball joints because of the longer leverage of the wheel being farther out. If you baby the car it’s not a big deal....if you auto cross it it is.
.
Thought I might go the wheel spacer route to keep it simple. It would take a bit of Engineering and a competent Welder, but, widening the K-frame an inch is within reason. I share the OP's concern: I don't like the way the wheels are tucked under the car either.

But the exact kinematics are unknown, might be better or worse without at least any computer analysis.. I personally would go at least two inches, and use a large dia rim with needed offset, which is my plan.
