Hello everyone I am hoping you guys can help me with doing a dual master cylinder conversion on my 61 Starfire, currently I have the single master cylinder that I would like to change to a dual master cylinder but yet keep my drum brakes, (I am not doing a disc brake conversion at this time and may not do it at all unless I have to)

Please any and help is appreciated

I have looked through the threads concerning this but it seems everyone is doing disc brake conversion

It's the same procedure, all you do differently is use a drum-drum master cylinder. Even a power brake set-up is very similar, again, you must use a PB master cyl. You can get them in drum-drum- and drum-disc.

Ty for the reply
The problem I'm having is that my single master cylinder has four bolt holes that attaches to the vacuum booster and I cannot seem to find a dual master cylinder with that setup

If two of the bolts/studs are in the right positions, just use them. Also make sure the pushrod length is correct for the new plunger and the distance it must travel. You can use a longer pushrod with a bolt pattern adapter (make it yourself) if needed.

I just used a commonly available booster and master. IIRC, I just had to oblong a couple of the original mounting holes.
