What parts do I need to switch to the bigger discs on my 69 rr,I already did the swap from a 76 duster. Car doesn't stop as good as it did with drums thought maybe bigger discs would help.I've tried different masters,the only thing I didn't change was my distubution block,but I put on a adjustible on brake brakes.Looking for ideas? THANKS EDDIE B

Naturally, you will be needing the 11 3/4 inch rotors, and the "taller" caliper mount brackets.
Whatever type caliper you are using, the pin type, or slider type, will determine what brackets you need.

Thats interesting as it would seem that going from a drum brake to even a 10 inch disc would benefit your braking system.

Maybe the 10 inch disc would probably be better at repeated numerous stops than a 10 or 11 inch drum as maybe heat would effect the drum more than the disc setup?

drums require a lower line pressure to operate than discs...my dad once told me that drums "self energize" meaning that as the shoe grabs the drum, they rotate a little, which pushes them into the drum harder...could this be why they need lower pressures?

when you changed masters, did you change the size, or simply buy a new one of the same size?

I've had three different sizes without any difference
