OZ 8 Spoke Alloys for S3C

[Swift]

Anyone know if there's still a source out there for the OZ 8 spoke alloys as fitted to later S2/S3/S4s ? One is particularlly pitted and don't think it will polish up or be able to be skimmed/re-lacquered. Don't seem to be able to get them from Oz-racing anymore. Is my only hope a second hand one ?
