Spare Part advice for DBSV8/AMV8

[crypto]

Looking for a pair of front discs for a DBSV8 / 1971 (identical to the AMV8 later model).
Are there any replacement parts available (apart from the works service) or exists a modification kit to replace the original brake system ? Are there any second hand part dealers (apart from puddleduck) ?

Thanks Peter

Have a look on ebay, most suppliers put their stuff on there
