Not sure what your plans for the car are, but I'll throw this out there because you're talking about welding on your own lower control arm tabs. The factory sway bar and sway bar tab locations limit your tire width up front pretty substantially, as in, 245's won't fit. Now, that's basically only a consideration if you plan on running 17" rims or larger up front since that's what it takes to run 245's up front inside the fenders.
If you are leaning more toward pro-touring though, I would either use the Hellwig 55917
Hellwig 55917 Hellwig Motorsports Tubular Sway Bars | Summit Racing, which was designed in league with a member here so he could run wider tires up front, or the Hotchkis 67-72 bar
Hotchkis Sport Suspension 22385F Hotchkis Sport Suspension Anti-Sway Bar Kits | Summit Racing
Both of those bars fit the 67-72 K member and use a sway bar tab location that's pretty much the same as the later 73+ cars. Since you're welding your own tabs on either way, this would be the time to move them if clearance for wider tires up front is a consideration. If wider tires aren't a consideration, then the Hellwig #5906 will do the job nicely.
As for the brakes, just run them to the rear and use '69 Camaro disk hoses. This is the info you want, courtesy of DoctorDiff. He also sells longer steel braided hoses for that application
As for Chevy parts, well, let's get real. You're going to buy them from a company that also makes Mopar hoses, they're just a section of rubber hose with connectors on the ends that happen to fit both a Camaro and a 67-72 A-body with the calipers mounted to the rear. The only difference from the Mopar part is the length of the hose.
