I bought the calliper mounting brackets, bolts and correct size spacers from west midland rs spares for 25 quid. Then i bought second hand callipers from scrap yard for 50 quid, rs2000 hand brake cable, rear disc and pads for a 2 wheel drive cossie from andrew pages knocked up a couple of copper brake lines but you may be able to use your original if they have not rusted away. Think it cost me about 150.
