1966-67 HCS convert brakes to dual master cylinder

[66hcs-conv]

Hi all,

I would like to convert our power, single master cylinder to power, dual master cylinder brakes.

Currently have power drum brakes on our '66, 289, which I prefer to keep.

BUT all the power, dual cyl. masters that I have looked at or measured, will not fit between the firewall and left front shock tower.

Anybody done a conversion, or have any info regarding a product that will fit?

THANKS, Dave
