Master Cylinder question.

It should work ,I just went through an ordeal trying to find the correct master cylinder for my 68 Cuda w/disc & drum. The main difference you`ll find is the reservoir for the front brake is generally larger than for the rear, since you have sometimes eight pistons moving, versus the drum/drum where you have two wheel cylinders.The drum/drum master cylinder will have equal size reservoirs and the disc/drum will be about 70frt/30rear. You might want to have the master cylinder that has the asymetrical reservoirs for that reason. As far as the pushrod it can be used with either master cylinder unless you`ve gone aftermarket and gotten away from the factory style master cylinder.
