You're right there L.A.B. - My bike has 6ca points fitted so I thought to replace with same and ordered 6ca (not knowing that they were probably not the original). It then followed that I should replace the caps/condensers which I assumed were also 6ca but as often seems the case with this old bike , ''nothing should be assumed''-the caps/condensers were 4ca ones. So I at least have the pairing correct now and new so will adapt as best I can hoping the coils are ok now. Must say I wasnt really aware that this site carried these type of spares and will check it out as well in future. Muchas Gracias!
