Power to Manual conversion questions

Hello,

Am am looking at converting my brakes from power to manual. The car is a 67 Valiant with 170 slant 6 and factory power front disc brakes.

This is temporary measure to give me time to find a replacement booster or get mine re-manufactured. Therefore I don't want to modify my original hardware/lines/etc so that I can directly revert to power brakes when the time comes, although I may be running the manual set up for a couple of years before I am in a position to revert to power...

From what I gathered, I need:

• a new "disc-drum" Master Cylinder with 15/16" bore (smaller bore to reduce pedal effort required)
• a different MC push rod, probably an adjustable one
  
• new brake lines from MC to front distribution block/tee
  
• a new MC gasket (plastic type used on all 60-76 A/B/E Bodies)

Then it should simply be a case of removing the original MC/booster/bracket assembly and bolting the new MC directly onto the firewall. There seems to be differences at the firewall between manual and power brakes. The bracket and MC bolt patterns are different for a start so I assume I will need an adapter plate (I can get one manufactured locally). So first question: are they any other modifications that I need to plan for in that area?

These are the bits I am planning to get:

• Right Stuff Detailing DBMC15 Master Cylinder, 15/16" Bore, Front port: 9/16 in.-18 threads. Rear port: 1/2 in.-20 threads.
• Mopar Performance adjustable push rod P4510640
• Classic Industries MC Gasket MD2092

Anyone used these? Are they correct and suitable for what I am trying to do?

Many Thanks in Advance.
