as others have done I used large waterpump type pliers lenghtwise on the old pads after heating with a heat gun.came out easily.then heated the new pad.slipped the lower edge in then worked the upper edge in with a small tip screw driver.used an old brake arm clamped in a vise to make it easier to apply pressure.porkchop BMX had the kool stop pads in stock-exact shape & size.
