I just found out that my wife got me a Porter Cable 7336 Sander/Polisher for my birthday. I want to be very happy, but I asked for the 7424 Orbital polisher. I did some research and found that the body and the motor is the same on both units, but the pads are different. Can I just put the polishing pads on the 7336 and have virtually the same polisher as the 7424?
