4 piston to single piston swap. 72 Demon

I forgot to mention;
I was so busy finding fault with the 73Up stuff, that it slipped my aging mind. The KH stuff has been trouble-free for me to the tune of 17 years and 125,000 plus miles. That's Zero maintenance required.And no, I have never had a moisture issue with DOT5.Nor the so-called compressibility.I do have the Teflon-lined front hoses. Awesome street brakes with the 10 x 2.5s and 295s out back doing a good portion of the work!I have never had a car that braked; better, harder,or in a shorter distance.And I think I may have only ever been in one other comparably stopping street car,since 1969. I think all cars should have bigger tires and harder working brakes, out back. I mean think about what that P-valve is doing. It is preventing the rear from skidding the tires and initiating a spin.Wouldn't more rubber back there have been a better idea? I thought so, and that's partly why I worked so hard to get the bigger boots back there. Well that and spinning out on every turn-under-power, was getting old........lol
