There are (presumably) two outputs from the new master cylinder, one from the front reservoir and one from the rear reservoir. One of these is for the front brakes, and one is for the rear brakes. If one reservoir is larger than the other, this one is for the front brakes. Is is important not to swap them around. If the aftermarket MC has equal size reservoirs, check the instructions for which one is for the front brakes.
So, that covers the two inputs for the proportioning valve/distribution block. There should be three outputs -- one for the single brake line that runs to the rear of the car, and one for each side of the front brakes. These two should be on one end or side of the block, away from the single output which is for the rear brakes. These three lines would already be existing, attached to the old distribution block, which would only have a single input. If you haven't done so already, you need to remove the old distribution block, which is no longer needed.
If the fitting sizes don't match up, then the kit should have supplied adapters for your application. If it didn't, then you should contact the manufacturer for the correct specification adapters, or find someone who knows what is what -- you don't want to just mix-and-match from the bins at the hardware store -- many plumbing adapters may have what seems to be the right thread, but will not seal properly in a high pressure situation like a brake line.
Whether they are power or manual brakes is irrelevant.
I have 65 cuda singl master cyclinder! went with duel mas.disk brake conversion kit (power). the por. valve i got is cast! there are 5 ports! two 1/2" ports, Three 3/16! the 1/2" one on top i put to mas.the one on the back i cant match to any lines! the front line on pass.front doesnt match anything on por.valve either! do these two go together with 7/16 to 1/2" adapter? everything is new! can anyone send me pictures! REMEMBER these are power brakes(disk FRONT and REAR) and mastercyclinder is duel and the PORTIONING VALVE IS THE CAST ONE!
