Replace all rubber bushings, install new shocks, replace all worn hardware (bolts, washers, etc and probably a good idea on a 30+ year old car anyway) most noticable difference will come from installing a new set of coil springs. Be careful when ordering springs, most "performance" springs will actually make the car sit lower than the factory height, thereby completly defeating the end result you desire, there should be a few places where you can still get the original factory springs or exact reproductions. Good luck!
there are 4 nuts under the car...
how to raise the front end of my 1973 impala
The bumpers for a 1972 Plymouth will fit a 1973 Plymouth duster with a little fabrication.
try manciniracing.com and see if they offer it.
all depends on the shape it's in and dodge never made the duster, plymouth did.
As long as it's from a 2-door Dart, it should fit.
727 automatic.
They should be interchangeable
D70-14" or 735-14"
Yes. Any 73 and up Duster or Valiant hood would fit.
Try the library and get a chiltons manual for your car.
That all depends on the engine you have and the rear gearing in the rearend.
