Aftermarket brakes for a 70 Dart?
I like the 73,74 a body Disc set up but I am a little frugal.You would need the upper control arms with the bigger BJ from the same car. I currently use KH on my Ragtop and Wilwood on my hardtop/ I did have a 69 dart that had the 74 set up and I loved them.
You don't need the large ball joint UCA's, you can use a ball joint adaptor if you're really frugal.
And if you're frugal, you shouldn't be running the Wilwoods anyway. The price for the 11" Wilwood kit for the KH disk spindles is $988, and you still need to spend another $70 on their brake hoses. So you're at $1,058. And here's the other thing, your wheels MUST have a hub bore of 3.050". That's huge. It eliminates every stock wheel ever made, and quite a few aftermarket wheels as well. Here's the pricing, the hoses are in the "required parts" section.

You can get the 11.75" DoctorDiff kit, with everything you need- knuckles, upper ball joint adaptors, new lower ball joints, stainless steel hoses, for $745. Now that doesn't include a master cylinder or prop valve but neither does the Wilwood kit. Or, you can skip the ball joint adaptors and buy the large ball joint UCA's for another $248, after you subtract the cost of the adaptors that's $970. So not only cheaper, but you get all new ball joints and upper control arms out of it, the larger wheel bearings on the later knuckles and larger bolts for the lower ball joints. Plus the replacement parts are cheaper to find if you need them. Heck for a little more you could get a set of QA1 UCA's and take care of the positive caster issue you'd have with the stock UCA's.

I have manual brakes and run Wilwood 6 pistons on the front and smaller on the rear. No issues at all.

That kit uses the later 73+ spindles though, so you'd need to add that to the price of the kit
