Well this is going about as well as I would have expected. All the traditionalists spewing abject hate because they don't understand and only like stock cars with hockey pucks on 14" rims that handle like absolute garbage.
I agree with
@DionR, wide body kits and fender flares can look good but it they have to be functional, you have to make it part of the whole purpose of the car. Like anything, if you just slap it on there it will not look good. But, if you lower the car and fill out the flares then they can look good.
There aren't a ton of examples, but I'll post some pictures/renders of the kind of thing you need to do for them to look like they belong on the car.
This is obviously an E-body, but if you look up the HRG "Fishtail" project you'll find this 'Cuda. This is a magazine build basically so there's tons of pictures of it on the internet. It's not the most functional of builds but they incorporated the flares into the rest of the build.
Then there's some renderings by an artist here
https://www.artstation.com/artwork/kaa4y , with several A-bodies. The "Fishtail" rendering was done by him. Again, the traditionalists will hate these regardless, but that's their opinion and like my opinion that 14" rallies are the dumbest, ugliest wheel ever made by Mopar that opinion is not shared by everyone.
There's this Duster, which apparently has a BMW V12 in it. Not a ton of info on it.

Honestly, I think the last one shows the problems with using a generic flare. In order to look good, the flare has to fit the car well. The imports that generally look good with this kind of modification have flares the are made specifically for that make/model, where because this isn't a common modification for a Mopar muscle car the readily available flares will all be generic, and will fit the car like a generic flare (not well). That said, it looks like those rear flares actually fit pretty well, what brand are they?
That's why the renders look so much better, because they've got a flare that fits the body style. Which you'd have to custom make if you really wanted to go that way.
Long story short, if you just slap on some flares to cover your poor bodywork it will look exactly like you slapped on some flares to cover some poor bodywork. If you want them to look right, you'd be looking at new wheels, tires, suspension modifications, etc...
