It really depends on what you want to do with the car. For a street car I like the reliability of the factory brakes.
With your 73+ disk spindles you can use the later B/R body 11.75” disks, they use all stock parts and with 2.75” piston calipers they work really well on an A body. I ran them on my Challenger on the street for 70k+ miles with 275/40/17’s up front, that car stopped very well. And I ran them on my Duster before I upgraded again to DoctorDiff’s 13” cobra style brakes. The 11.75 factory disks are a great brake set up. Yes, they’re heavier than Wilwoods. But on the street that doesn’t matter. And you can get the parts just about anywhere, which can matter for a frequent driver. They work fine with 15” rims too.
I also really like the 13” DoctorDiff cobra style disks I have on my Duster. They stop the car really well and have a good feel with the 15/16” master cylinder. But they require a 17” wheel, minimum.
Full disclosure, I am not a fan of Wilwood. Their mopar hubs have a 3.05” hub register, which is even larger than the already large stock hubs and limits your wheel selection pretty significantly. I don’t like the safety wired stuff on the street either. And frankly, they’re pretty expensive for what they do. I’d much rather give my money to DoctorDiff, so that’s exactly what I do.
