Brakes: conversion Power to Manual

Hi Guys,

i´v got a 1968 Valiant 2dr sedan, factory power front disc brakes (KH Setup), rear end is a Ford 8.8 with discs.

My new engine does not make enough vacuum for the power brake booster, it does not work properly.

So i´d like to change the setup to manual master cylinder and loose the power equipment. I read that i need a new master, new pushrod, and an adapter to mount the new 2 bolt master cylinder to the firewall.

Can somebody tell me the partnumbers for these parts? I´d like to verify what i´ve read online with first hand experience.

Also, what size diameter master is better suited? There is a 15/16" one and a 1 1/32" one available as far as i know. I tend to the smaller one due to higher brake pressure at given force from the foot...

Thanks for information!

Michael
