I was wondering if its possible to put power brakes on my 70 dart?and if so whats intailed in doing so?
thanks

You'll have to replace the rod between the pedal and MC with the longer one required for the power booster. Then install the power booster and bracketry, then the master cylinder. You'll need new longer lines between the master cylinder and distributionblock/proportioning valve because the master cylinder will be in a new place closer to the front of the car.

The swap itself is not too complicated. I would try a junkyard booster on your current master cylinder. Try to get one from a 73+ car because they are a bit shorter (but wider) to save some engine compartment space. You can get a booster & MC for $150-200ish rebuilt from kragen if you want ot go that route, but you would still need the bracket and rod.
