1965 Valiant brake woes

Professor Fate said
By "stock", do you mean a '66 and earlier distribution block, or a '67 and later factory block?
The early block will do you no good, since you are upgrading to a dual-circuit master- it will not have the correct number of ports for the new system, nor will it separate the two circuits. If a '67 and up drum/drum distribution block is not available, go with the "t" setup I described previously.
Best of luck!

I've asked my buddy what year his distribution block is from. He has a Barracuda, but I'm not sure what year.
If I'm basically going "stock" drum/drum but with a '68 style dual circuit master cylinder, are these the type I'm looking for? ( I was gonna post some OEM used ones from eBay, but they're either the same price as the new ones or in ROUGH condition!)

**EDITED**
I contacted Inline and here's what they suggest:
