Need a little more information. Do you have a anti-sway bar? Do you have 15 inch wheels? Do you want stock parts so you can buy replacement parts at a NAPA or do you want something that looks aftermarket?

DoctorDiff probably has everything you need so start there. If that doesn't turn your crank there are a couple of other choices such as Baer.

I'm thinking the '73-76 A body slider discs would fit. If so & you get a used setup get some rebuilt calipers at your parts house for a '76 A body as they have 2.75" calipers as opposed to 2.60" calipers for more front bias (almost always a good thing). they are identical in price & external dimentions/fitment.

Yeah they'll fit if you can find them. A body stuff is hard to find in wrecking yards anymore. DoctorDiff has reproduction stuff all new in the box.

If it was me I'd put the '73+ knuckles on there with 11.75 factory rotors and front hung calipers. Classic Mopar Action disc swap. Find the parts used or buy reproductions from DoctorDiff.

this is exactly what i did on my 67 coronet.

already had the FMJ spindles, you can order new spindles from Doctor Diff.
got the 11.75" rotors and adapters from Doctor Diff.
Also used his stainless brake hoses for front mounting the calipers because i think the brake hose routing is cleaner this way.
calipers were just remans for a 76 dart which should be a 2.75" piston.

I bought a whole kit from dr. diff for my 68 charger and was very impressed at how well it bolted together and how it worked. He helped me identify my existing booster because he said a dual diaphram booster would work better in my application.
Turned out I had the single. How many guys would have told you that. And I probably wouldn't have been happy with the pedal pressure to stop if I would have stayed with the single.

Bottom line it stops like a modern car now.

Dr. Diff is the only way to go. Cass (owner) is fantastic. I would step up to a 17" wheel and run the Cobra setup front & rear, but here are the 'budget' minded kits for both wheel sizes.

17" wheels -
