Hi Mark, great old school wheels which really suit a Saff. They do come up for sale but not very often. I would be patient and keep looking as the idea of welding up and re-drilling a set of wheels would not be great and would probably cost a lot of money. I have the old style OZ racing Cronos wheels on my Saff and I was lucky to find a single one exactly the same as mine for the spare on E-Bay in Germany. Might be some Rondells available in Germany?
