Front suspension conversion

I agree with Jdmopar, and use the front brakes from the '73-'76 Dart/Valiant. To use these you will also have to use the upper control arms from these cars as the late model disk brakes use a larger upper balljoint that won't fit in your original upper control arms. Darter6 is also giving good advice if you have a larger budget. However many of the aftermarket kits advertised prices don't include the proportioning valve nor master cylinder so be aware of that as you add up the cost when making your decision.
