A question I should of asked before

its a 70 dart its going in, the axle shafts just came from a demon. and where VERY good value.

changing the front brakes and wheels is something im planning on avoiding for now. as i dont want to loose my KH set up.

BBP may be something i plan on doing later on, but right now its the SBP im after.:thumbsup:
Fair enough.
I can see where you are coming from now.
The stock A-Body width diff makes perfect sense on a '70 Dart.
As you go along, you might seriously consider mini tubbing the car and moving the springs inboard for extra clearance so you can fit bigger tires in there, with of course the right offset wheel.
You can have your existing wheels modified for fairly cheap if you know of a good machine shop/welder/fitter.
Just another suggestion FWIW..........
How about some pics of the car?
