Up grading to dual master cylinder

[tcom]

Good morning,

I want to upgrade to a dual cylinder in my '46. A buddy with a '32 roadsters did a very sanitary install of a master cylinder with an integral reservoir. and residual valves. it has a three bolt flange and looks like Mustang (?) unit.

He got it from Roadster Supply. Has anyone installed one in a '46 and if so does anything have to be modified or brackets fabbed?

Thanks,

tony
