65 Fury brake question

[mr. fix it]

Thanks for all your input guys, what i deceided to do is order a duel m/c for a 67 with drum brakes my brakes are 11x 2 3/4 on the front and 11 x 2 on the rear. I have a picture i will post of my splitter block, iam going to plug the outlet to the rear brakes and put a union on that line to extend it to the m/c. Now iam wondering about my main line to the splitter is 1/4 inch and all the brake lines are 3 /16 should i replace the big one with a 3 /16 or leave it ? Thanks for any help.

it will need to be replaced with 3/16" and an adapter to make it work or if you get lucky enough, a good supply chain will have the larger flare nut with the 3/16" center.
Got mine from Pep Boys a few years aback

Be sure to add a few loops for vibration purposes/
I used a piece of 1 1/2" abs pipe with a notch in it to make mine.
Again, it's important to get a Drum/Drum M/C making sure that you run the rear reseviour to the front brakes and the front reseviour to the rear brakes into the metering valve(distribution Block)
