got a brake question..

Get a drum master cylinder for 67-up. I went with a 75 because the lid doesn't use bolts, it uses a clip. Run a line from the MC to the old junction block and cap the rear brake line port. Then run a line direct from the MC to the rear line. I normally replace the whole line to the axle. Depending on which MC you buy will determine which is the front and rear reservoir. The bigger line will be for the front. Other then bending the line and loosening the old ones its a bolt in. The drum splitter valve is not needed. It is not a proportioning valve just a warning switch for the loss of pressure.
