Drawer Glide?

I have uploaded three pictures below. One picture is of my drawer area, the second is of the part I need, the third is what it looks like with the part missing. I have numerous "drawer glides" that have broken off (don't know if this is the correct term). My drawers are now really rough when sliding them in and out. Is 32-083 the part that I need? Will exact size matter? Lastly, do you all carry one that screws in like the one in my picture?
Thanks
Justin
