Brake Shoes

The pictures are exactly what mine look like. The pads have plenty of wear left and the only reason I was going to replace the pads was I had a wheel cylinder bad on one side and a wheel seal on the other. As I am trying to restore this 65, I am trying to take care of any problem as I get to it.
The groove measures exactly in the center of each pad.
Now do I replace them with smooth pads or keep looking?
