Have 4 speed Brake/Clutch pedal setup, need Single Brake pedal

I have the clutch/brake pedal setup for my 69' Dart and I am going with an automatic transmission, so I need to swap out this setup for the single brake pedal setup.
The one I have is in perfect condition so I'm looking for one in similar shape. (Do they make a new reproduction of these?)
Let me know what you have.
Thanks.
