Front Disc Conversion for '65 Valiant

I need to replace the master cylinder on my '65 Valiant & thought that it would be a good time to convert to dual diagonal braking W/front discs.








I would rather use OEM parts to simplify future servicing.

What would be involved as far as part & adaptors?

I eventually want to put an 8 3/4 dif out back & hop up the 225 Slant 6 W/a beefed up 904.

1st, I want to make the handling/braking up to the task.
