63 Rivi Dual Master Conversion

[RivNut]

The old master cylinder looks to have had better days and I want to convert her over to a dual master.
Has anyone done this, or could anyone please suggest which cylinder to try?
Thanks!

I replaced my 62' lesabre's master and booster froma cadillac. They all bolt up the same, would work great.

I've done at least a dozen of these
use a 67 buick big car master- the used 2 different ones, bendix and moraine.
you must use the bendix master.
use the original booster, BUT YOU MUST USE A DRUM/DRUM PROPORTIONING VALVE.
Buick did not use a prop valve untill 67.
you can use one from 67-72 if they are 4 wheel drum
feel free to contact me if you have any questions
