Hi Kathie. The 'back clamping' or 'side clamping' refer to how the various feet are clamped to the presser bar on your machine. There's a little screw to hold them on. Some vintage singers (the early 66-1s for example) many times used back clamping feet. The new vintage machines used side clamping. It's just how they fit onto the machine. You can't put a back clamping foot on a side clamping machine or vice versa.
