Has anyone done that?  Thinking of doing that and would like to call on anyone who has and what problems I could encounter.

I bought a front disc/power booster kit from one of the Thunderbird supplier (they retired, I think Hill’s acquired them) back in 1999. It used a disc/drum dual master and the booster on the front disc only. I don’t recall if there was a different rear wheel cylinder (for balance adjustment) or if it would be different with the front booster. But most of the bird suppliers would know.
