Front disc brakes

Hey guys i'm in need of help, Installed 4 wheel disc brakes on my 69 dart. On the front i did the larger upper ball joint and 74 upper a arm and spindle. Now my front wheels track wider than the rear wheels about half and inch. How do i correct this with the disc brakes setup intact? The disc set up is a jegs or summit setup, I have to check my receipt to be positive!

A 1/2" wider track on the front wheels then the track on the rear wheels will not cause a problem with the way the Dart performs as long as the tires clear the fenders. Unless the difference really bothers you, I wouldn't change anything, nor would I be concerned. Gene

Later A bodies had a wider front track stock.

You could put oem a body small bolt pattern disc brakes on it with machined 5 lug mustang rotors to reduce the track width. but you would have to locate all the parts and spend $$$

A wider front track is a good thing since the car is nose heavy. It might look a little funny but it is actually a very good design practice. If you mostly care about looks then you can use spacers in the rear or buy wider rear wheels or swap in a longer rear axle or all sorts of other solutions.

The issue with the wider front track is if you lower the car very much you increase the chance that the top of the tire will rub on the fender.
