autozone does have brake pads for the W123... i only buy my tail lamp bulbs from them.. their are places to get parts online.. fastlane, **************.com, me... other places

also doing the pads on the W123 is the easiest car to do it on, tap out two pins, drop one side in at a time, put the pins back in, new wear sensors... dont forget the anti squeal paste.. and your done
