Look on Macs wesite, they may have a diagram with a pad kit. Pad kits I've used have chassis diagrams with the various pads locations. Also remember, the pads have a shoulder moulded around the hole which locates the pads into the corresponding chassis hole. When I say lift it some (the body), I mean enough to be able to get good access for removing stuck pads, replacing the new ones and as mentioned you'll have to loosen most of, if not the whole car. I'd remove all the body bolts and the front fenders will have to be separated too. You don't want to lever it this way and that and end up twisting the thing and screwing door gaps etc.
