I am getting different thing told about weather or not 1979 Chrysler New Yorker(R Body),Front Spindals will fit on a 1970 Dodge Dart.I am being told the angles are wrong and the upper control arms will not take the bigger ball joints.If I am right all I need is new upper ball joints. HELP  

I have set on my 68 valiant you will need later A body A arms 74 on I think they will take the bigger upper balljoints and you will need B body lower balljoints kind of limits the steering but if you grind down the stops on the lower balljoint a little bit they work great you will also need the bigger bolts that hold the spindel to the lower balljoints hop this helps
