i recently bought a lovely set of RC35s from a member and there is a part missing which i don't know the name of. I've spoken to Pace but they've sent me the wrong bits and my local bike shop haven't been particularly helpful. So - apparently it is a tear-drop shaped slice of Aluminium that sits on the bit where you attach the brake and into which you position the brake 'pin'. Can anyone tell me what it's called? My retrobuild has ground to a halt and this is the last bit i need... Many thanks
