I have always fitted D8HA plugs and never had a problem but is there an alternative that people have tried. I know the answer will be stay with what you are happy with but just asking.
The 1963 Owners Manual quotes C7HW as being the correct plug. This is a 10mm plug and the equivalent would have been a D7HW.
Modern plugs have a wider heat range than the 1960s issue so my guess is that the heat range of the D8HA or a D8HS would overlap that of the D7HW anyway.
If it works OK don't change it.
