Nice car!
Usually the big deterrent to disc brakes on our early cars is having to switch from 13” wheels to at least 14”. You are already making that upgrade. I have had a ‘66 Valiant convertible that I upgraded to the larger 10” drums brakes (like on your car) and it worked ok. But I now have a ‘66 with the original Kelsey-Hayes front disc brakes and I really like them. They are
far superior to the drum brakes and I love the “feel” or modulation of these brakes. And this improved braking performance is period correct as these were an option and most often on a Formula S.
I’m working on the dual reservoir brake master cylinder upgrade to eliminate the “widow maker” single reservoir version. I just don’t like the idea of one leak means absolutely no brakes.
And our old cars are very unsafe compared to a newer car. Just one example is they do not have collapsible steering columns. So I want all the help I can get in traffic with todays faster and better stopping cars and huge trucks.
