I am restoring an original LA built 67 Nova SS currently to driver quality. I just replaced the original calipers and cleaned up the distribution block and master cylinder, but there was no proportioning valve used like the one you have pictured. The car I am working on is manual brakes, front four piston calipers, rear drum. On most cars I assemble, I use that proportioning valve, but they are usually single piston calipers and running a booster. I have never used that brass distribution block with exception to later model cars. You can get away with using your original cast piece. I'll snap some pictures of this car tomorrow if you'd like as it is quite original.
