check out ebay always sets on their cheap. It may also be worth posting in the 'Wanted ' section of the FTOOC (UK). Lots available usually as most people change for newer styles.
Hey Gerry,
check out zacobs fto for sale post. he says he still has original set of mitsu 16" alloys he's willing to throw in with the car if you buy it. maybe he'll sell them seperately.
