I hope I do not add to the confusion here ... there is a different between the shims (credit card sized, flat pieces of metal) and the spring (y-shaped, goes into tiny holes on the sides of the pads themselves). The shims will come in a kit, 2 for each pad, so 8 for front kit, 8 for back kit. The springs come with the fitting kit, together with the little metal clips that hold the pads to the calipers. Also separate kit for front and back.
I recently have had to replace them -ALL- on my 94NA and here are the part numbers and descriptions. (as well as price I paid at partznet)
All I can say is that without the correct combination of springs and shims installed, I tried everything to make the brakes stop squealing ... nothing worked. With these, went away right after install. (I'm using OEM pads.)
