As the discs and hubs, with wheel bearings, are standard Volvo you don't have much choice. Luckily they are now available new at a much lower price than the originals that had to be refurbished by shrinking on new discs. The new ones are all in one piece for about half the price. I put some on my Amazon and they are good. If you have managed to do a conversion that uses the later seperate discs please let us have the details.
