Dave, I have no idea about South African motor factors but I would try brake manufactures on-line catalogues for the equivalent pads, like Ferodo, Mintex, Brembo et al. Then check your local stockists. For instance I believe your brakes from Ferodo are labelled FDB 370, Brembo I think are P23 070 ( I would double check those just to be on the safe side). Sometimes with the catalogues you will have to put in the original part number, not the subsequent replacement number but it's a suck it and see situation depending on the manufacturer.
