I'm running a 69 front disk brake set up and just replaced the front pads. I used "Wagner" and I cannot get the outer pads to keep moving around and causing a slight "clatter" or "clicking" noise at slow speeds. Even after re-bending the tabs and adding goo they still click. Not sure if it is the brand of pads or I'm missing something? Any suggestions would be appreciated.

You have a problem I've never run into but I do have a couple of thoughts.
First, are you sure the pads are at fault not the wheel bearings? The way the pads are built, the warning bars are meant to drag along the rotors when the pads are worn out. The scraping/squealing noise is obvious and not in my experience a clicking sound. That said if the clicking goes away when you apply the brakes, it is likely the pads. To check the pads you can always apply a thin coat of paint to the edge of the warning bars where they would meet the rotors. After driving, if the paint isn't scraped away, something else is going on.
I assume you've spun the wheels with the front end off the ground to see if you can isolate the clicking.
Second, did you install new hardware with the pads? It's possible the clicking is the result of some sloppiness in the hardware.
Third is a dumb question but did you put wheels on that are for a disc brake car? if not, check the inside of the wheels for shiny spots indicating interference.
If it were my car, after making these checks, I'd install a different brand of pads.

Thanks, - I know where the noise comes from, but don't know how to fix it. I can raise up the wheel and move back and forth and can hear the [censored] outer pad click.

When you bend the outer pad tabs down you need to have someone stand on the brake pedal otherwise they will never quite tighten up enough. Since you already did it you may need to straighten them back out some. also using large channel locks and a strong grip helps.. and if your grip is not strong enough take a large chisel and drive it between the lower part of the pad and the hat/hub of the rotor to drive one side of the pad up as far as it will go then have someone hold down the brake pedal and bend the tabs down with a dull chisel or a flat punch making sure the backside of the tab is not bent at an angle inward. Remove chisel and repeat on other end of pad.
