Switching to Kelsey Hayes setup

I got it all finished today after work and took it out for a drive. Feels great. It was raining so I didn't get on the brakes to much but so far they work awesome. Good investment I feel.

I'm doing a Kelsey Hayes disc conversion on my 65 Dart. Currently it has 10" drums, the single circuit master cylinder and no vacuum assist. The pedal effort is too much for my taste. I'm trying to decide whether to use the vacuum booster from the 1972 or leave them manual.
Prior to your converstion did you have a dual circuit master cylinder already?

Did you see any reduction in pedal effort after your conversion?
