58 Brake up grade

[Straight8john]

I am going to re-work my brake system on a 1958 special. New ss lines wheel clyinders and a dual chamber master clyinder.
Can't find a three bolt dual master that would matchup any suggestions. The old system is just standard bakes.

Any info will be helpful, Thanks

I am in the same boat. Did you ever source a dual reservoir MC and if so from where? Cheers. Michael.
