I've managed to find a supplier in Italy who has stock of the original Clutch Bearings required for the Flavia 815 variants. His shipping costs were a bit silly, but if I take 3 or 4 bearings at the same time he will ship all for the same price as one.
This would equate to ~£77 a bearing if we get 4 takers. Anyone interested or do you have a cheaper solution for replacing these bearings?
On the same subject, does anyone know where to source the clutch spigot bush for this car?
