cheers, i dunno how much it cost, i did alot of the polishing myself, like the wheels and alternater(before it was chromed) and it will still cost another £120 to get the alternater refurbed with new bushes and bearings but a rough price( if you didn't polish anything and just bought it) would be around £750 ish i guess but if you want just the front of the manifold done i would diy it, you can get polish to cut the cast on ebay, or do as i did , the old fashioned way with sand paper and patience
