disk brake options (factory) 73 Scamp

First: Thanks to all for the input on the original post.
Second: Since original post, Have purchased and restored a complete front UCA/ spindle set up from a later model that I purchased. Has all new bearings, ball joints, etc. Ready to install when I get time from customers projects. Also bought a narrowed 8.8 disk brake rearend for the car and changed to a 3.08 from the 3.73 to be better behind the /6. So Limited slip, disc brake, etc. Also purchased an aluminum master cylinder kit. Hope to get time this summer to get the 4 wheel disc brake setup installed and run all new brake lines to get much better stopping power.
