Camry 2008 brake pad anti squeal springs

[Joy]

hi just did a brake pad replacement on my 2008 camry acv40r.  couple of questions

there were no existing anti squeal springs (the ones that push the pads away from rotors) should this have been there ?. I have been riding on this set of pads for almost 50k with no issues.  if i need buy them are they only available at toyota dealerships ?

2nd question .. my replacement brake pad is Bendix OE .  Online research seems to indicate that its good to replace the clips that these pads sit on. bendix pads didnt come with it. I cant find any on both the online stores i look at currently( supercheap and sparesbox ) . just wondering where can i get them ?

any assistance would be much appreciated.
